What condition is characterized by a prominent bump on the heel known as Haglund's deformity?

Haglund's deformity is indeed characterized by a prominent bump on the heel, commonly referred to as a pump bump. This condition arises due to the abnormal growth of the bone on the back of the heel, often as a result of repeated friction or pressure from shoes, particularly high-heeled or rigid footwear that compress the back of the heel.

The term "pump bump" is a colloquial name for Haglund's deformity, reflecting the condition's common association with certain types of shoes. The prominence of the heel is typically accompanied by pain, inflammation, and irritation of the surrounding soft tissues, including the Achilles tendon.

Understanding this condition helps identify the right treatment and preventive strategies, like choosing appropriate footwear, to alleviate symptoms and prevent further irritation.
