Insertional heel pain
Retrocalcaneal bursitis is swelling (inflammation) of the fluid-filled sac (bursa) at the back of the heel bone (calcaneus) under the Achilles tendon.
A bursa acts as a cushion and lubricant between tendons and muscles sliding over bone. There are bursas around most large joints in the body, including the ankle.
The retrocalcaneal bursa is located in the back of the ankle by the heel. It is where the large Achilles tendon connects the calf muscles to the heel bone.
Repeated or too much use of the ankle can cause this bursa to become irritated and inflamed. Possible causes are too much walking, running, or jumping.
This condition is usually linked to Achilles tendinitis. Sometimes retrocalcaneal bursitis may be mistaken for Achilles tendinitis.
Risks for this condition include starting an aggressive workout schedule, or suddenly increasing activity level without the right conditioning.
