I am in the same boat as you. I couldn't believe it when I logged in and read that you have shingles to. I was diagnosed to late for any medication, I was really bummed. I had severe back pain for three days along with tingling and itching on my left side (I also had two small bumps that looked like bug bites) so I went to the doctor (my doctor was not available so I had to see someone else) who diagnosed a kidney stone. The bumps got bigger and spread and the itching was horrible so I went back to see my doctor who diagnosed shingles and then informed me it was to late to treat (it had been over a week from the first spot). So I'm waiting for the spots to clear and the itching to go away. It really stinks because the rash is on my waist line and my pants irritate it something horrible. The cortisone theory makes me wonder if that's what triggered my shingles. I had an injection in my shoulder this past year, I think it was in the fall (Fibro Fob strikes again). I won't be doing that again. I also thought that you could only get shingles once, I really don't think I want this again. I'll not be getting another injection. Stress, not sure how to avoid that.
One top of the shingles, I do have a kidney stone confirmed by a CT. It's small and not causing any problems right now but who knows what the future will bring.
I hope you feel better soon and know that you do not suffer alone.
I got shingles when I was 24 yrs. old. I did not feel well and then I broke out in a rash, midback, traveling to my right side. Then it formed big red bumps, and blisters. I did have deep pain at each bump. It was when I was starting my first job as a nurse and I was so scared and which caused stress. I feel that is what triggered it.
Went to the Dr. - he took one look at them, and stated you have shingles, there is nothing we can do for it and it will run it's course. Oh- OK. That was almost 30 yrs. ago.
Hope your feeling a little better-
