Capsulitis is an inflammation of the ligament 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. Wearing high heels or other poorly fitting footwear and performing repetitive activities that bend the toes, such as ladder climbing, are also known causes.
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.
