i have large bumps on the back of my heels where the back of my shoes are. I previously went to ortho re this (about 2 years ago) and they told me calcium deposits. It is larger and much more painful, i did everything they said, toe curls, stretching exercises, boot at night for the plantar facitis, that has gone away but, the lumps on the back of my heels are more painful than ever. My shoes fit, i have tried inserts, help, is there not something else that can be done!!??
You may be able to have arthroscopic surgery to remove them. The surgery is not particularly complicated or invasive...it's usually done on an outpatient basis and you're usually walking again within a week. According to one article the deposits usually do not return.
Check with your doctor and if she/he agrees then good luck :)
