Joint pain all over the body can be caused by a variety of conditions, including infections, inflammatory diseases, autoimmune conditions, and complications of some chronic joint disorders. Here are some potential causes of joint pain all over the body:

• Autoimmune conditions: Autoimmune conditions cause the immune system to attack healthy cells and tissue in the body, leading to inflammation and pain in the joints. Examples of autoimmune conditions that can cause joint pain include rheumatoid arthritis and lupus.

• Infections: Joint pain can be a symptom of infections caused by a virus or bacteria. Reactive arthritis is a type of joint inflammation that can occur after an infectious illness, particularly food poisoning or a sexually transmitted infection.

• Inflammatory diseases: Inflammatory diseases such as ankylosing spondylitis and adult Still disease can cause joint pain all over the body.

• Osteoarthritis: Osteoarthritis is a common type of arthritis that happens over time when the cartilage, the protective cushion in between the bones, wears away. This can cause joint pain and stiffness, particularly in the hands, feet, hips, knees, or spine.

• Tendon injuries: Injury to the tendons can cause joint pain, as tendons are the extension of muscles that attach on a bone, and these often attach around joints. This means you may feel like the pain is in your joint, but it’s really a muscle.

• Gout: Gout is a common, painful form of arthritis that causes a chemical called uric acid to build up in the blood. This acid then leaks into the joints and makes crystals in the body’s joints, fluids, and tissues. The crystals can be very painful and cause lots of swelling, pain, and redness in the joints, such as your big toe, hand, wrist, or knee.

If joint pain is interfering with normal daily life activities, it is important to talk to a doctor about the problem. A doctor can determine the underlying cause of the pain and recommend appropriate treatment to relieve pain and maintain healthy, functioning joints.
