OP: In reading your info I don't think I saw any mention of surgery done to the body? Is that true?

My worst issues came on after hip replacement in 2010, and before I've dealt with OA anyway. Now all worse and plenty of neuropathy. And I was also told I have Fibromyalgia that was in 1999, so it's a bag of a lot of stuff in my life. And advanced age, 83 soon.

On the Sciatic nerve, my issue came on after hysterectomy in the 80's I was in my 40's, so for me it's been decades of sciatic nerve damage. I'.ve done a lot of body work in my life and sadly the damage does not reverse. It's all management....but you are young.
