Arthritis affecting the feet

Osteoarthritis, psoriatic arthritis, and gout often cause foot pain, which if severe can affect mobility.

Your foot has 33 joints, 26 bones, and more than 100 muscles, tendons, and ligaments. Foot pain can be a sign of arthritis. Here are some common conditions.

Gout is caused by a buildup of uric acid in the joints or surrounding connective tissue. It affects the joints and usually starts in the big toe, causing pain and difficulty walking. Gout can be caused by genetic factors or by food intake. If left untreated, the disease can progress and attack other parts of the body such as the ankles, knees, and elbows.

Osteoarthritis is a degenerative joint disease in which the tissues in the joints break down over time. It is common in older adults. People with osteoarthritis often have joint pain; after rest or inactivity, the joints become stiff for a short period of time. Joint pain often occurs in the bottom of the toes or between the foot and ankle.

Rheumatoid arthritis is a chronic autoimmune disease that occurs when the immune system mistakenly attacks the synovial membrane of the joints, causing inflammation, swelling, pain, and stiffness in the joints in the morning. The disease usually begins between the ages of 35 and 60, and affects women more than men. Symptoms of the disease are symmetrical, such as pain in the same location on both sides of the body, often in the joints of the feet and hands.

Psoriatic arthritis is a complication of psoriasis. The symptoms of psoriatic arthritis are similar to those of rheumatoid arthritis, but it is less likely to affect the joints. Typically, people with the disease have swollen fingers and toes and pitted, scaly, or discolored nails.

Ankylosing spondylitis is a chronic systemic inflammatory condition that occurs 2-3 times more often in men than in women. Initial symptoms often occur in the area where tendons connect to bones, pain in the heel or arch of the foot, and pain when walking.

Post-traumatic arthritis of the foot or ankle can weaken the joints, leading to the risk of osteoarthritis. This condition can put extra stress on the feet and accelerate wear and tear. Symptoms include swelling, fluid buildup in the affected joint, and difficulty walking.
