One explanation for the bump on the back of your heel may be a condition known as Haglund’s deformity. Also known as “pump bump”—on account of how often this deformity occurs in women who frequently wear high-heeled pumps—the primary symptom is an enlarged bony protrusion on the back of your heel. This is typically accompanied by heel pain. Pump-style shoes often have rigid backs and the resulting friction and pressure can contribute to the development of this condition. Other causes include a foot structure with high arches, tight Achilles tendons, and a tendency to walk on the outside edges of the feet. Given that there may be other causes of a bump on the back of your heel, it is important to see an expert Sugar Land podiatrist like Dr. Marco Vargas at Vargas Foot & Ankle Specialists who will provide an accurate diagnosis for you.
