Hi, I have been diagnosed with fibromyalgia for 2 years now but feel that there is something else and that this is a quick fix diagnosis. Today my cousin told me that she has been diagnosed with Hashimotos. We have lots of family members with thyroid issues (but I don t know who my dad is) but all the test came back normal for mine and hers. Is there a chance that this is what it could be? I am also vitamin D deficient and need to take 8,000 IU a day. When I have a flare up I get a headache down the left side of my head from the top to below the chin, teeth, ears and all. Is this normal for Fybro? I also have muscle weekness, low heart rate, exhaustion and many more symptoms. I was told today my dr. that if I had Hashimotos that I would have a severe sore throat and my heart rate would be fast. Is this true? Just want to be diagnosed instead of always pushed under the rug if possible. Any suggestions are helpful. Is Gluton free diet the way to go? Thanks for your help in advance.
