Twink - Unfortunately, they have not figured it out other than the good sized goiter I have on my thyroid. Labs for thyroid are all normal. They did find that my insulin is high but my blood sugars and such are normal. It's just really odd. I go back to the endocrinologist next week for a follow up. Maybe this new one can shed some light on what is going on. I was much, much thinner when you last saw me. The clothes from that time are packed away in my "hope" box (as in I hope I can wear them again).
