Fibromyalgia and hypothyroidism...are they linked?

Hi there, i was just wondering how many of you have hypothyroidism along with fibromyalgia. My doctor seems to think there is some correlation. I've been reading posts and I found that the two things everyone seems to have in common is that we were all go-getters before the fibro. People that push their bodies...maybe too much!? The other thing seems to be the fatigue and exhaustion. I do get exhausted from dealing with the pain to get things done, but for me the lack of energy only happens when my thyroid is high. It took me a few years to figure out the difference! Does anyone else have hypothyroidism as well?
