I have thyroid nudules, non toxic diffuse goiter (those were diagnosed tn May this year). Have autoimmune thyroid antibodies (the TSI antibody is very high..this is the one that causes Grave's disease). In the past I had hyperparathyroidism caused by a benign tumor on one of my parathyroid glands I had surgery for that in 2010 at the Norman Parathyroid Clinic in Tampa, FL. That condition caused me to have severe osteoporosis at a younger age than usual. Yet with these problems, my TSH , T3. T4 reverse T3 and T4 are all within normal range. The endocrinologist I saw in May said I probably will develop an autoimmune thyroid condition in the future either Grave's or Hashimoto's . I have read in researching that there seems to be a link between autoimmune thyroid antibodies and Fibromyalgia

I've had underactive thyroid too for many years

I have hypo thyroid, was diagnosed with that years before Fibro, but then I think that I have had Fibro for a long time, but I just wasn't diagnosed.

I have hypo thyroid and take meds to control it, I think we all have a hormone imbalance that cause fibro to worsen.

This is interesting - I had my thyroid removed 3 years ago because of malignant cells in my throid. I was put on Synthroid and thought I have tolerated it very well. But... 21/2 years ago I started having severe body pain; muscles, joints etc. It has taken 2 years of complaining to the doctor and many tests to be given the diagnosis of fybromyalgia - really though the process of elimination.

I have tried Lyrica but the weight gain and sleepiness were unendurable, so I have decided to try some exercise and Tylenol. Because of the episodic nature of the pain it is hard to tell if anything works, or what causes the episodes.

Having read your story I am going to talk to the Thyroid doctor who hasn't been involved in the pain issues.

Also has anyone else noticed that almost all the posts on this website are from women? (and most a lot younger than me) I wonder how much of this is hormonal?
