Many peole on this message board have mentioned that the shots can break down the fatty pads and also destroy fascia.
If you check the survey results that Scott did on heelspurs.com you will see that there are other things to try before cortisone shots--arch supports, stretching, rest, acupuncture to name a few. Some people like Birkenstock shoes--Arizona style and some people have been helped with glucosamine.
Good luck.
