Had the injections in my neck a few months ago, seems to have worked. Injections in my shoulder (2) within the last few months, not working as well as the pinched nerve. This latest procedure was supposed to be a routine colonoscopy but after re-reading the post-procedure report, it seems that it took much longer than normal because they found so many things that needed to be dealt with. 4 polyp biopsies, a polypectomy and an endoclip.
