Metatarsalgia is a condition characterized by pain and inflammation in the ball of the foot, specifically around the metatarsal bones. This discomfort often arises from excessive pressure on the foot, which can be caused by factors such as improper footwear, high-impact activities, or foot deformities like bunions. Symptoms of metatarsalgia include sharp or aching pain, swelling, and a feeling of having a pebble in the shoe. Treatment typically involves rest, ice, proper footwear, and sometimes orthotic devices to provide better support and alleviate pressure on the affected area.
