The stiffness and pain that accompany arthritis are particularly noticable when they affect the feet.

Here are possible reasons behind foot arthritis, courtesy of the American Podiatric Medical Association:

• Foot injuries, particularly if they were not treated properly.
• Viral or bacterial infections that affect the joints.
• Inflammatory bowel disease.
• Prescribed medications or use of illegal drugs.
• An autoimmune disease.
