I am worried that I may have thyroid cancer. At least twenty years ago, I started to get a lot of pain in my eyes. Two Opthamalogists (sp?) suggested my eyes were fine and that it could be my thyroid causing the pain. My family doctor said my blood tests were fine. I then went to get my eyes checked about a month ago and told the Optometrist about my eye pain that was more frequent and worse. I told him that my doctor said my levels were fine and he said that doesn't mean it isn't caused by your thyroid. Now, I am waking up in the morning or middle of the night hot - once soaking wet - and the heat seems to be coming from my burning throat and radiating to my chest. I am also experiencing some thinning of my hair and eyebrows and have chronic fatigue. Any ideas?
