I usually post in the Fibro section, but I saw the title and had to reply.
You mentioned that you developed Shingles after a injection in your back. I don't know what kind of shot it was, but I had bursitis in my shoulder yrs ago and the dr gave me a steroid shot. A wk later I developed Shingles, never thought there was a connection. Yrs later I read that steroid shots can bring on a case of Shingles. I have been blessed w/ about a dozen bouts of Shingles and never had another steroid shot. I have also been told you can only get Shingles once. NOT!
Last yr I had gone to an ortho due to problems w/ my shoulders and knees. First thing he said, steroid shot. I said no and told him why. He basically smirked and said how helpful it would be. I still refused and that was that.
This isn't meant to scare you, just to give you a heads up. I never had pain patches given to me for Shingles, just oral med and it made me sick. I have had the patches this past yr for my shoulder, knees, and Fibro pain and yes, they are so expensive.
Glad you're feeling better, hope you never get them again.
God bless. Alice.
