Metatarsalgia is a general term used to describe pain in the ball of the foot. Usually the pain is located under the 2nd, 3rd or 4th metatarsal heads. Metatarsalgia is often caused by excessive pronation (arch collapse) and the resultant friction and shearing forces.
A differential diagnosis of metatarsalgia is ‘Mortons Neuroma’, which is a nerve entrapment causing localised pain. In addition to pain, numbness between toes may be experienced, and in extreme cases swelling of the affected phalanges (toes) may occur.
