"Metatarsalgia" is an ill-defined condition. Scranton defined it as "pain in the fore part of the foot", but other definitions would be more precise in terms of nature and location of discomfort. Pain in the first ray is generally understood to be excluded.
Metatarsalgia should be understood as a symptom rather than a diagnosis. It is a diagnostic challenge and a good example of the importance of careful history taking and examination in the foot, as it has many causes and often more than one is present.

Metatarsalgia is a common overuse injury described as pain in the forefoot associated with increased stress over the metatarsal head region. Metatarsalgia often is referred to as a symptom, rather than as a specific disease. Common causes of metatarsalgia include interdigital neuroma, metatarsophalangeal synovitis, avascular necrosis, sesamoiditis, and inflammatory arthritis; however, these causes often are diagnosed separately.

in the normal foot, metatarsal heads bear one half of a person's body wt, when the foot is plantigrade;
- the first metatarsal normally bears half the wt of the forefoot;
- long 2nd metatarsal can contribute to pressure under metatarsal head;
- limitation of dorsiflexion (from heel cord contracture or ankle impingement can contribute to diffuse metatarsalgia
