<s>[INST] I have extreme fatigue, full body aches (dull, head to toe), heat intolerance GA (I do live in southeast GA) sometimes I HAVE to sleep on my stomach because sides and back hurt. all blood work including thyroid comes back perfect. Whats wrong with me? [/INST] Hi I did review your concern mam. as you rightly did thyroid abnormalities are the most common cause of the problem you are having. However some of the other cause can be anemia, fibromyalgia,polymyalgia and so on. I would recommend you to first get a CBC to seem if your blood work is fine. Fibromyalgia is a clinical diagnosis and gabapentin/lyrica works fine for chronic controlwish you all the best </s>
