What should you know about subcutaneous calcaneal bursa pain?

The calcaneus is the heel bone. A subcutaneous bursa lies between the skin and the back of that bone, where footwear and repeated rubbing can irritate it. Pain may be local, tender to touch, and associated with a small soft swelling. Achilles tendon problems, skin injury, infection, gout, or another bursa can cause similar symptoms, so the exact position matters. Joint swelling may be described as heel swelling even when the joint is not the source.

Choose footwear that does not press on the back of the heel, reduce rubbing, and pause activities that repeatedly load or strike the area. A clinician can check the skin, bursa, Achilles tendon, and ankle movement. Anti-inflammatory medication may be considered when safe for you. A cortisone injection or joint aspiration is not automatically suitable for a superficial heel swelling; the diagnosis and infection risk should be reviewed first. Avoid trying to puncture or massage a hot, very tender lump.

Seek prompt medical attention if the heel becomes increasingly red or hot, swelling spreads, fever develops, fluid drains, or pain becomes severe. Arrange assessment after a wound, bite, or significant injury, or when walking becomes difficult. Sudden inability to push off the foot needs urgent evaluation.

Is the pain coming from the superficial bursa, Achilles tendon, skin, or joint? Could infection be present? What footwear or activity changes are useful? Would medication, injection, or aspiration be safe at this site?
