With fibromyalgia...not all spots will ache all the time...it will come and go and it is related to certain foods.
Have you seen a neurologist? Just so that other things can be ruled out.
Back to fibro...I was dx'd many years ago and suffered terribly...pain is no more as I changed my diet to eat foods that do not cause inflammation...think about it...inflammation starts in the digestive tract and from there migrates...
I have said mentioned this several times in different posts but it is the truth. Ice cream will cause great discomfort so I know if I have it that I will be painful for a few days...so the question is...pain or no pain..ice cream or not...
If it is truly fibro...you CAN get your life back...I did.
