Bump on back of heel

Haglund’s deformity is characterized by a benign bump that forms at the back of the heel. It’s common among women who wear high heels, having earned the nickname “pump bump.”
The American Podiatric Medical Association suggests:
Health Tips
* Use orthotic inserts, heel pads or arch supports inside shoes to help relieve pressure on the back of the foot.
* Take an anti-inflammatory drug or apply a topical cream to ease pain.
* Wear a walking boot or soft cast, which may help a sore and inflamed bump heal.
* Ask a podiatrist if surgery is needed, if none of these remedies work.
