Welcome.
I'm a recoverying alcoholic/addict, been sober/clean 10 years and have MS and fibro which I was diagnosed with 2 years ago.
Sounds like you are heading in the right direction and I have always been honest with my Doc/s due to fear of relapse.
I expereince varying degrees of pain and am on a daily dose of nortrip - other than that I use wheat packs and lots and lots and lots of rest.
Let us know how it goes with your Doc.
