I had 3 Corizone injections over a period of 14 months. That coupled with a 15 minute set of am & pm exercises, I have very little trouble. The pain is gone and only once in a while the tingle comes back, when standing too long. I have Spinal Stenosis and I am 64 years young. Going for a hip replacement in March '01. The shots and the exercises seems to have been my answer. Bob W.
