1wk after a severe ankle sprain, still swollen and bruised. skin is tender and feels like burning. cracks appeared bellow the swelled area. normal?

Yes: Especially for severe ankle sprains. The cracks are from the swelling. I would have your ankle examined and possibly x/rayed to endure there are no broken bones.

No: I would not call this normal. You should see a podiatrist for evaluation.

Have it evaluated.: Pain may last a long time following a foot or ankle injury. An x-ray can show if there is an underlying fracture. You may have a soft tissue injury if it is just a sprain and may have damaged the muscle, tendon, or ligaments in the area. Have it evaluated by a professional and get the appropriate treatment.
