Achilles tendonitis is diagnosed by a history and physical examination of the patient who describes pain at the back of the ankle with walking and/or running activities. The pain generally will be associated with an increase in running or jumping intensity or frequency. The pain from Achilles tendonitis is often so severe that running is impossible and even walking is uncomfortable.
The common cause of a painful bump on the back of the heel is called Hagland’s deformity. This is due to an enlarged bony prominence on the back of the heel. It can involve the entire back of the heel or just a portion of the back of the heel, usually on the outside portion of the heel.
Over 95% of all heel pain is diagnosed as Plantar Fasciitis. This is best described as an inflammation of the ligament that runs from the heel to the ball of your foot and helps support your arch. The bottom or inside of your heel may hurt when you stand.
