Just wanted to post an update for you all.
I saw my doctor today regarding my FM and asked her the burning question (no pun intented, haha!) "Why am I so HOT!?"
She told me that there are a few possibilities. It could be thyroid related, a medication side effect (Amitriptyline has increased body temp. as a side effect) or it is very possible that it is just one of those nasty quirks that goes along with FM. She hasn't had many patients complaining of over heating with FM but she wouldn't rule it out. It is not uncommon for chronic pain to increase body temperature.
I wish I could have more answers so we can all get some relief!
Feel free to keep on posting comments to this sharepost and the previous post about FM and our body temperature. It has been very interesting (and comforting!) to read all the replies.
