It may not seem much to you, but I brushed my teeth and shaved with my right hand this morning. I admit that there was as much head lowering as arm raising in the exercises but it is a great improvement on the beginning of the week. I also managed to get a decent kip.
I remember that I have had cortisol injections when my shoulder has flared up before, so I am self diagnosing impingement syndrome. Treating it, as I have, with non-steroidal anti-inflammatories and rest seems to be working. I wonder what I can do longer term? Then again maybe I should just bite the bullet and accept that I will get it every few years if I crash and burn in the course of undignified exertions.
