I was already struggling with pain and fatigue when I hurt my foot. I thought I’d stepped on a shard of glass, but my dry foot had cracked naturally. I slathered my feet with hand cream and seemed fine. I would walk down the hall or across the kitchen without a problem. Then some step apparently no different than the others would result in stabbing pain. I would limp for a short while, then the cycle would start again. That’s when I learned about heel fissures.
