I have not had that many, but quite a few. The very first one gave some relief for about 2 weeks. Then, nothing. Ever snce, none have helped. I just had another round a week ago...again, no help. It remnds me of the old saying about insanity: doing the same thing over and over, and expecting a different outcome. Ha! Why don't I learn?
Why did you keep having injections if they didn't help? Just desperate and hopeful, like me? lol.
