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.
Plantar calcaneal bursitis is a medical condition in which there is inflammation of the plantar calcaneal [1] bursa, a spongy fluid filled sac that cushions the fascia of the heel and the calcaneus (heel bone). It is characterized by swelling and tenderness of the central plantar heel area. It is sometimes called 'Policeman's heel'.
It is also known as retrocalcaneal exostosis, Mulholland deformity, and ‘pump bump.' It is a very common clinical condition, but still poorly understood. Haglund's deformity is an abnormality of the bone and soft tissues in the foot. An enlargement of the bony section of the heel (where the Achilles tendon is inserted) triggers this condition.
The tendon is covered by the fascia and skin, and stands out prominently behind the bone; the gap is filled up with areolar and adipose tissue. A bursa lies between the tendon and the upper part of the calcaneus. It is about 15 centimetres (6 in) long.
The differential diagnosis for heel pain is extensive and includes pathological entities including, but not limited to, the following: calcaneal stress fracture, septic arthritis, calcaneal bursitis, osteoarthritis, spinal stenosis involving the nerve roots of lumbar spinal nerve 5 (L5) or sacral spinal nerve 1 (S1), calcaneal fat pad syndrome ...
Achilles bursitis is bursitis (inflammation of synovial sac) of bursa situated above the insertion of tendon to calcaneus. [1] It results from overuse and wearing of tight shoes. [ 2 ] [ 3 ]

Immune deficiencies, including HIV and diabetes, can also cause bursitis. [1] Traumatic injury is another cause of bursitis. The inflammation irritates because the bursa no longer fits in the original small area between the bone and the functionary muscle or tendon. When the bone increases pressure upon the bursa, bursitis results.
