Pump Bump (Haglund's Deformity)
This is typically seen on the back of the heel as an enlarged swelling underneath the Achilles tendon. Usually caused by an enlarged bone mass with overlying tissue swelling on the back of the heel, which may take years to develop. The bump typically becomes enlarged and painful from rubbing on the back of shoes or "pumps." Conservative treatment consists of heel lifts, shoe padding, orthotics and occasionally injections. If this fails, surgery may be necessary to remove the bone and tissue mass.
