Capsulitis is an inflammation of the tendons on the bottom of the foot. It is usually caused by trauma or abnormal structural functioning, which overstretches the ligament that attaches one of the toe bones to a metatarsal bone. Trauma to the area is the general cause of this problem although the trauma can be as benign as wearing an ill fitting pair of shoes. Often it is the result of poor biomechanical functioning.

Pain in the forefront of the foot is the most common symptom of capsulitis. Capsulitis is often misdiagnosed as Morton's neuroma because of similar symptoms

Noninvasive treatments are used to resolve capsulitis, including use of cortisone injections, taping to off load the joint and possibly orthotics if a biomechanical problem is found on examination. Although very painful, this condition is generally quite easily treated.
