has been given so many names and causes over the yrs. Many many yrs ago this Fibro stuff was called rheumatism...then along the way it was given the name Fibroitis...and then some 10-15yrs ago Fibromyalgia was the name given to it all.... One rheumy I have seen, an older woman, called it fibroitis, my younger rheumy calls it Fibromyalgia...so depending on the age of docs, the name can be different. In my grandmothers and mother's day it was called rheumatism... So what I'm getting to, all the rheumatic pain down the side of my arms and upper back is about gone since Anatabloc... Rheumatic diseases (rheumatism) are painful conditions usually caused by inflammation, swelling, and pain in the joints or muscles. So even though many here say it's not inflammation, I have to disagree...and believe a lot is inflammation re: fibro stuff... I still have pain and STIFFNESS in knee joints and lower back which are arthritic but is reducing.....spinal stenosis pain/burning is about gone..
