Has anyone else developed significant bumps on the back of the heel of your feet? Something caused these to develop many years ago and I saw the term PUMP BUMP. It described a growth on the back of the foot commonly seen on ladies who frequently wore pumps. I have worn heels off and on for the last 50 years but never was able to wear for any extended length of time on the infrequent times I have been able over that period of time. It was stated that wearing pumps "irritated" the back of the heel. It never felt painful but something caused them to develop on booth feet.
