Pain at the posterior heel or posterior ankle is most commonly caused by pathology at the posterior calcaneus, the Achilles (calcaneal) tendon, or the associated bursae. The following bursae are located just superior to the insertion of the Achilles tendon [1, 2, 3] :
Subtendinous calcaneal bursa - This bursa (also called the retrocalcaneal bursa), situated anterior (deep) to the Achilles tendon, is located between the Achilles tendon and the calcaneus. 
Subcutaneous calcaneal bursa - Also called the Achilles bursa, it is found posterior (superficial) to the Achilles tendon, lying between the skin and the posterior aspect of the distal Achilles tendon.
Haglund deformity (prominence of the posterior superior calcaneus) is not a true synonym for calcaneal bursitis, but it can be a closely associated condition.
Inflammation of the calcaneal bursae is most commonly caused by repetitive overuse and cumulative trauma, as seen in runners wearing tight-fitting shoes. Such bursitis may also be associated with conditions such as gout, rheumatoid arthritis, and seronegative spondyloarthropathies.
In some cases, subtendinous calcaneal bursitis is caused by bursal impingement between the Achilles tendon and an excessively prominent posterior superior aspect of a calcaneus that has been affected by Haglund deformity. With Haglund disease, impingement occurs during ankle dorsiflexion.
A study by Lohrer and Nauck indicated that retrocalcaneal bursa pressure rises in patients with chronic retrocalcaneal bursitis, which in turn, the investigators suggested, can cause an impingement lesion on the anterior Achilles tendon. 
Calcaneal bursitis is seen somewhat frequently, particularly if the clinician has a predominantly musculoskeletal practice.
See the list below:
No mortality is associated with calcaneal bursitis.
Morbidity is associated with progressive pain and limping (antalgic gait) in patients who have not received adequate treatment. If chronic inflammation also affects the distal Achilles tendon, rupture of the tendon may occur.
No race predilection has been documented.
Calcaneal bursitis is observed in men and women. However, some increased risk may be incurred by women who wear high-heeled shoes.
Calcaneal bursitis is commonly observed in middle-aged and elderly persons; the condition is also seen in athletes of all ages.
