Fibromyalgia?

As I'm lying here in the dark wide awake I'm wondering if my CFS is more than CFS. Lately I've been experiencing a lot of joint and muscle pain. I'm wondering if I have fibromyalgia. I was looking at the symptoms last night on the Mayo Clinic website and it looks possible. I hope it's not that. I'm going to have to do some more research.

What I read did say that CFS, IBS, and emotional stress can be risk factors and triggers and I'm thinking I have a lot of those things and other things on the checklist so I wonder...
