Retrocalcaneal bursitis

Retrocalcaneal bursitis is an inflammation of the bursa located between the calcaneus and the anterior surface of the Achilles tendon.^[1] It commonly occurs in association with rheumatoid arthritis, spondyloarthropathies, gout, and trauma.^[2]

The pain is usually on the back of the heel and swelling appears on lateral or medial side of the tendon.^{[citation needed]}
