Fibromyalgia - fibromyalgia n hair loss

Hi..just recently in the last 2 days... was in the ER twice, for achy hands, legs, weekness, tingling in hands, feet, etc. My joints crack and all that good stuff. The doctor thinks its just stress...but he also mentioned fibromyalgia. They took blood from me 18 times..it was all normal. My hair is also coming out ALOT...way way more than usual. Is this a normal sign of Fibromyalgia? What can I do about it? They said not to stress...but this is stressing me out...lol. Please help me...Im currently on B2 vitamin, and magnesium. thanks soo much.
