How does fever cause arthritis?

Fever is typically not the direct cause of arthritis. Arthritis is a condition that affects the joints of the body, causing inflammation, pain, and swelling. It is often caused by autoimmune disorders, infections, or wear and tear of the joints.

High fever can be a symptom of certain illnesses that may be associated with, or lead to, arthritis. For example:

1. Rheumatic Fever: This is a rare condition that can develop in children and young adults a few weeks after a streptococcal infection, such as scarlet fever or strep throat. Rheumatic fever can cause joint inflammation, along with other symptoms like fever, rash, and fatigue.

2. Viral Infections: Some viral infections, such as influenza (the flu) or parvovirus, can cause temporary joint pain or inflammation as part of the overall illness.

3. Septic Arthritis: This is a serious bacterial infection that can affect one or more joints, causing fever, chills, and severe pain in the affected joint.

4. Other Infections: Certain infections, like Lyme disease or hepatitis, can sometimes lead to arthritis as a complication in some individuals.

It's important to consult a healthcare professional if you're experiencing fever, joint pain, or other symptoms that may indicate arthritis or an underlying medical condition. Appropriate medical evaluation can identify the cause and recommend the most suitable treatment. Self-diagnosis and self-medication should be avoided, as the type of arthritis and its appropriate management may vary depending on the specific condition.
