My opinion is that it is progressive! When I was first diagnosed, I did not have all of the tender points, or at least I did not feel them. Now, I can feel all of them. I don't need to be touching them, I just feel the ache. Also, my sensitivity to touch, sound and smell have greatly increased. I don't believe that it increases to the point of being fatal, but I do think that as we age our week spots become vulnerable to the fibro. I do think that we can slow the progression by eating right, exercising and staying away from stress or triggers. We all need to learn what sends us into a flare and then we need to avoid it, if possible. I'm still working on that one .
