Yes, some forms of arthritis can cause fever and chills, especially when inflammation is high or infection is present.
Joint pain that burns or throbs is already draining. When fever and chills join in, the mix can feel scary. Many people with arthritis wonder if these symptoms belong to the same problem or point to something new.
This guide explains how arthritis and body temperature changes connect, when mild symptoms are part of a flare, and when they hint at infection or another illness. You will see clear red flags, questions to ask your doctor, and simple ways to track symptoms at home.
Understanding Arthritis And Systemic Symptoms
Arthritis is a broad term for conditions that cause joint pain, stiffness, or swelling. Some types stay mostly inside the joints. Others affect the entire body and can trigger fatigue, low appetite, weight change, and sometimes fever and chills.
Common categories include osteoarthritis, inflammatory arthritis such as rheumatoid arthritis, crystal arthritis such as gout, and arthritis linked to infection. Each group behaves differently and carries a different risk of temperature changes.
| Arthritis Type | Main Features | Fever And Chills Pattern |
|---|---|---|
| Osteoarthritis | Wear-and-tear joint pain, stiffness after rest, bony swelling | Fever and chills are uncommon; look for another cause |
| Rheumatoid Arthritis | Swollen small joints, morning stiffness, fatigue | Low grade fever can appear during active inflammation |
| Psoriatic Arthritis | Joint pain, skin plaques, nail changes | Fever may occur with widespread inflammation |
| Axial Spondyloarthritis | Back stiffness, pain that eases with movement | Low grade fever is possible during flares |
| Gout | Sudden painful joint, redness, warmth | Fever and chills can accompany intense acute attacks |
| Septic Arthritis | Severe joint pain, swelling, limited motion | Often high fever and chills; urgent emergency care issue |
Systemic or whole-body symptoms such as fever and chills come from chemical signals called inflammatory mediators. These messengers circulate in the bloodstream and reset the body thermostat in the brain, which raises temperature to fight what it sees as a threat.
When people ask “can arthritis cause fever and chills?”, doctors look at the type of arthritis, other symptoms, and medicines in use before drawing conclusions.
Can Arthritis Cause Fever And Chills During A Flare?
During an inflammatory flare, the immune system becomes unusually active. Joints swell, stiffness worsens, and pain increases. At the same time, the same immune chemicals that drive joint inflammation can act on the temperature control center.
In conditions such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and juvenile idiopathic arthritis, a mild fever is fairly common during active disease. Chills can appear when the temperature starts to rise or fall, even if the thermometer number is not very high.
Many people describe a pattern of feeling washed out, losing interest in food, and then noticing a slight rise in temperature on their home thermometer. This pattern often lines up with sore, hot, or visibly swollen joints.
Medical groups such as the Versus Arthritis rheumatoid arthritis overview describe low grade fever as one of several whole-body features that can appear with joint swelling. That link between joint inflammation and general illness feeling is one reason doctors track symptoms beyond pain alone.
When Low Grade Fever Fits An Arthritis Pattern
A low grade fever often sits in the range of 37.5–38.0 °C (99.5–100.4 °F). With inflammatory arthritis, this type of mild temperature rise tends to appear with familiar flare signs and then ease as treatment calms inflammation.
Clues that a mild fever may relate to an arthritis flare include:
- Recent increase in joint pain, swelling, or morning stiffness
- Low appetite, tiredness, and general aching muscles
- Fever that seems to track with days when joints are more active
- Relief when prescribed anti-inflammatory medicine brings the flare under control
Even when the pattern points toward arthritis, your doctor needs to rule out infection, medication reactions, or unrelated conditions before assuming the cause. Never ignore a fever that feels unusual for you.
When Fever And Chills Signal A Different Problem
Some warning signs point away from a simple inflammatory flare and toward a more serious problem. These include higher temperatures, shaking chills, fast heart rate, or feeling confused.
Emergency warning signs include a very painful single joint that becomes red, hot, and hard to move, combined with fever or chills. That pattern raises concern for septic arthritis, which is an infection inside the joint and a medical emergency. The United States Centers for Disease Control and Prevention arthritis guidance stresses the need for fast care when a joint infection is suspected.
High fever with cough, chest pain, burning when you pass urine, rash, or stomach pain can also signal infections that sit outside the joints. People with arthritis, especially those on immune-suppressing medications such as steroids, methotrexate, or biologic drugs, can have higher risk for serious infection.
How Arthritis-Related Inflammation Affects Body Temperature
Inflammation is part of the immune response, and fever is one of its tools. When the immune system detects damage, irritants, or germs, it releases proteins called cytokines. These signals reach the brain and reset the thermostat in the hypothalamus.
Once the thermostat shifts upward, the body responds by narrowing blood vessels in the skin and causing muscle shivering. That is where chills come from. Later, when the body tries to cool down, blood vessels widen and sweat increases.
Inflammatory Arthritis And Cytokines
In inflammatory arthritis, immune cells stay active even when there is no infection to fight. They release cytokines such as tumor necrosis factor (TNF), interleukin-1, and interleukin-6. These same signals that damage joint cartilage and bone also affect the temperature control center.
This link explains why a person with severe joint inflammation can feel feverish, wiped out, and chilled at night even without an infection. Treating the underlying inflammatory disease often reduces both joint pain and whole-body symptoms.
Medication Effects On Fever And Chills
Medicines for arthritis can affect both the risk of fever and the way the body responds to infection. Non-steroidal anti-inflammatory drugs such as ibuprofen lower fever as they reduce inflammation. This can hide a temperature rise that would normally draw attention.
Drugs that weaken parts of the immune system, such as corticosteroids, methotrexate, JAK inhibitors, or biologic injections, can raise the odds of infection. That means even a modest fever or mild chills matter more for someone on these treatments than for a person who takes only simple pain relievers.
Can Arthritis Cause Fever And Chills From Infection?
Yes, arthritis can connect to fever and chills through infection in two main ways. The first is septic arthritis, where bacteria or another germ infects a joint directly. The second is an infection that develops more easily because the immune system is weakened by disease or medicine.
Septic Arthritis And High Fever
Septic arthritis often arrives quickly. A joint, often a knee, hip, or shoulder, becomes intensely painful. Even light touch or a small movement can feel unbearable. The joint looks swollen and warm, and range of motion drops sharply.
At the same time, people usually feel very ill. High fever, shaking chills, sweating, and sometimes nausea or confusion may appear. This combination needs emergency care, since joint infection can damage cartilage in hours and can spread through the bloodstream.
Emergency care teams treat septic arthritis with joint drainage and intravenous antibiotics. People who already live with osteoarthritis, rheumatoid arthritis, diabetes, or immune-suppressing treatment have higher risk.
Infections In People With Arthritis
Even when infection does not sit inside a joint, people with arthritis may run into more frequent or more severe infections. Inflamed lungs, frail skin, reduced mobility, and immune-modifying drugs can all play a part.
Common infections that cause fever and chills in people with arthritis include flu, pneumonia, urinary tract infections, skin cellulitis, and shingles. Monitoring temperature, breathing, and urine changes matters a lot if you receive regular immune-suppressing therapy.
Tracking Fever, Chills, And Arthritis Symptoms At Home
Good records help your medical team decide whether fever and chills match your usual arthritis pattern or hint at something new. Simple tracking habits can make appointments more productive and shorten the path to an accurate explanation.
What To Record Day To Day
A small notebook or app can store short entries. Try tracking:
- Daily temperature with a reliable thermometer, at the same times each day
- Which joints hurt, how much they swell, and stiffness length after waking
- Presence of chills, night sweats, rash, cough, shortness of breath, or urinary pain
- Medicines taken, doses, and any recent changes
These details help your doctor see patterns and decide whether symptoms fit an inflammatory flare, a medication side effect, or a likely infection.
When To Call The Doctor Or Seek Urgent Care
Many people with long-standing arthritis know their usual flare level and feel when something differs. Trust that sense and reach out for advice when patterns change.
Contact your doctor soon if you notice:
- Fever above 38 °C (100.4 °F) lasting more than a day or two
- New chills with sweats or feeling faint
- Shortness of breath, chest discomfort, or persistent cough
- Burning or blood when you pass urine
- New rash, severe headache, or neck stiffness
Seek urgent or emergency care right away for:
- Severe pain, redness, and swelling in a single joint with fever
- Very high fever, repeated shaking chills, or confusion
- Trouble breathing, chest pain, or blue lips or nails
These signs can point to conditions that need quick treatment, such as septic arthritis, sepsis, or pneumonia.
Managing Fever, Chills, And Arthritis Safely At Home
While your medical team checks for underlying causes, home steps can bring some relief. Simple measures can make fever and chills easier to handle and protect joint comfort at the same time.
Comfort Measures For Mild Fever
Drink steady small sips of water or oral rehydration solution to prevent dehydration. Dress in light layers so you can adjust as your temperature shifts. A lukewarm sponge bath or cool cloth on the forehead can ease discomfort without forcing a sharp drop in temperature.
If your doctor says it is safe, you may use over-the-counter medicines such as acetaminophen or ibuprofen within recommended dose limits. Always check that these drugs fit with your prescribed arthritis treatment and other health conditions.
Protecting Joints During Chills
Shivering and muscle tension can strain already sore joints. Wrapping knees, ankles, or wrists in soft blankets or wearing gentle compression sleeves may reduce shaking. Gentle range-of-motion moves, such as slow ankle circles or finger stretches, can keep joints from stiffening while you rest.
When chills pass and fever eases, short walks around the room can improve circulation and loosen tight muscles, as long as your doctor has not asked you to rest in bed.
Lowering Infection Risk Day To Day
Basic infection prevention steps matter even more when you live with arthritis and immune-modifying medicine. Regular hand washing, staying current with vaccines recommended by your medical team, and avoiding close contact with people who have flu-like illness can trim risk.
Healthy sleep habits, balanced meals, and gentle movement within your comfort range also support the immune system. None of these steps replace medical care, yet they give your body a better base when it needs to respond to stress or infection.
Working With Your Doctor To Clarify The Cause
Sorting out whether arthritis causes fever and chills requires a full picture of your health. Your doctor will combine history, examination, and testing to reach a safe explanation.
Questions Your Doctor May Ask
During a visit, expect questions about:
- When fever and chills began and how they change through the day
- Which joints hurt, how long morning stiffness lasts, and how symptoms affect daily tasks
- Recent travel, sick contacts, new foods, or animal bites
- Exact doses and timing of arthritis medicines and any missed doses
Honest, detailed answers make it easier to match symptoms to patterns seen in arthritis flares, infections, or medicine reactions.
Tests That May Help
Doctors often order blood tests such as a complete blood count, markers of inflammation, and blood cultures if infection is suspected. Imaging such as X-rays, ultrasound, or MRI can show joint damage or fluid buildup.
If a single joint is very swollen, a needle may be used to remove fluid for analysis. This test can distinguish between gout, septic arthritis, and inflammatory arthritis with similar symptoms.
| Symptom Pattern | Possible Source | Suggested Response |
|---|---|---|
| Mild fever with several sore, stiff joints | Inflammatory arthritis flare | Call clinic soon for review and flare management |
| High fever and one very painful red joint | Septic arthritis concern | Go to emergency care immediately |
| Fever with cough or shortness of breath | Lung infection or flu | Seek same-day medical assessment |
| Fever with burning urine or back pain | Urinary tract infection | Arrange urgent clinic or urgent care visit |
| Night sweats and weight loss over weeks | Chronic infection or other illness | Book prompt appointment with primary doctor |
Follow Up And Long Term Monitoring
Once the immediate cause of fever and chills is clear, follow-up visits help fine-tune long term care. Your doctor may adjust arthritis medicines, add preventive vaccines, or suggest screening tests based on your infection history.
Regular reviews of temperature records, flare patterns, and lab results give both you and your medical team a clearer sense of what feels typical. That way, any new bout of fever or chills stands out earlier and can be checked before it grows more serious.

Frequently Asked Questions
Can Osteoarthritis Alone Cause Fever And Chills?
Osteoarthritis usually stays inside the joints and does not raise body temperature. When a person with long-standing osteoarthritis develops fever or chills, doctors often look for infection or another condition as the main cause.
Fever in this setting deserves medical review, especially if pain or swelling changes quickly or new symptoms such as cough or urinary burning appear.
Do Biologic Drugs For Arthritis Hide Signs Of Infection?
Biologic treatments and some other disease-modifying drugs can blunt parts of the immune response. In some cases, they may soften typical infection signs, including fever. A person can feel tired or short of breath before a thermometer reading looks high.
Because of this, doctors ask patients on these medicines to report new symptoms early, even when temperature looks near normal.
Is A Low Grade Fever Every Evening Normal With Rheumatoid Arthritis?
Some people notice a mild rise in temperature in the late afternoon or evening when rheumatoid arthritis is active. That pattern can match immune activity that peaks later in the day. The reading often stays just above normal.
Even so, share this change with your rheumatology team, especially if the level rises over time, new symptoms appear, or medicines no longer keep flares under control.
Can Gout Attacks Cause Shaking Chills?
Intense gout attacks may trigger low grade fever and chills because the inflammation response is strong. The body reacts to crystal-driven joint damage in a way that can resemble infection from the outside.
A very painful red joint with higher fever needs urgent medical review to rule out septic arthritis, since the two conditions can look similar at first.
Should I Stop My Arthritis Medicine When I Have A Fever?
Do not change or stop prescribed arthritis medicines on your own, even when you run a fever. Some drugs must be paused during serious infection, while others can continue. The best choice depends on the drug type and your overall health.
Call your prescribing clinic or on-call service for tailored advice. They can review your chart and guide next steps for both fever care and arthritis control.
Wrapping It Up – Can Arthritis Cause Fever And Chills?
Arthritis and changes in body temperature can share the same roots in immune activity. Inflammatory forms of arthritis often bring mild fever and chills during active phases, while wear-and-tear osteoarthritis rarely does. Infection adds a different and more urgent layer.
By tracking symptoms, responding quickly to warning signs, and working closely with your medical team, you can reduce risk and gain clearer control over both joint pain and temperature swings. Prompt questions and early checks protect joint health and overall wellbeing.
