Causes of Metatarsal Joint Pain
Metatarsal joint pain commonly results from misalignment of the joint surfaces, which puts pressure on the joint lining and destroys cartilage in the joints.

Fat tissue, which helps cushion the joints when bearing weight, can be pushed forward under the toes, resulting in a loss of cushioning in the ball of the foot. This loss of cushioning normally occurs as many people age but makes people more susceptible to pain when the ball of the foot is stressed or injured repeatedly (for example, by running or by walking excessively). This loss of cushioning may lead to damage to the nerves of the foot Damage to Nerves in the Foot Irritation of interdigital nerves (in the balls of the feet) may cause enlargement of those nerves, causing pain in the balls of the feet.

Symptoms of Metatarsal Joint Pain
Walking is painful for people with metatarsal joint pain. The skin over the joint may feel mildly warm to the touch, and swelling may be present. Over time, pain and stiffening can be disabling.
Diagnosis of Metatarsal Joint Pain
A doctor's examination of the foot
Doctors usually can diagnose metatarsal joint pain based on the person’s symptoms and an examination, but testing is done if an infection or arthritis is suspected.
Treatment of Metatarsal Joint Pain
If present, treatment of underlying condition
Orthoses (devices placed in the shoe) usually provide effective treatment for metatarsal joint pain. Shoes that have thicker soles than normal and rounded heels (called rocker sole modifications) also help reduce pressure and abnormal motion.
Medications to treat the underlying inflammatory condition (such as rheumatoid arthritis Rheumatoid Arthritis (RA) Rheumatoid arthritis is an inflammatory arthritis in which joints, usually including those of the hands and feet, are inflamed, resulting in swelling, pain, and often destruction of joints.... read more ) may be needed. Sometimes corticosteroid injections can help.
Occasionally, when these measures are ineffective, surgery is needed.
