Hey Helluva... I'm just piping up re the steroid injections.
I had problems with my shoulder for a bit a few years ago and was offered a steroid injection (I have since had another for the same prob) and when I came out of the doctors surgery and told my partner he congratulated on being so brave. Puzzled, I asked him why (it was just an injection after all) and he told me steroid injections can really hurt. I had no pain from it and the relief in my shoulder seemed almost instant.
I had no side effects (two injections over a few years) and I would strongly recommend them if you are offered again - however, if I had to do a course of injections, I would reconsider... don't want too much steroids in ones system...
Wishing you a positive and healthful outcome from your lifestyle descision - great to be doing it with your husband - thats what I love most about cycling... it is another passion both my partner and I can share.
