Hello and Welcome
I have Fibro and MS. My biggest complaint is pain and fatigue. The pain is more Fibro than MS-like.
1. Pain all over - Yes.
2. Extreme dry eyes and mouth - No. Did your eye doctor give you any insight as to the cause of your dry eyes? Have you been tested for Sjogrens?
Have you had your thyroid levels checked? And screened for arthritis/osteoarthritis? This was part of my work up for Fibro along with LOT's of other tests including hormones.
Are you under the care of a rheumatologists? In my opinion, only a rheumy has the expertise to make a diagnosis of fibromyalgia.
