I haven't been feeling well for over a year. My doctor would tell me that I'm the picture of health. Last week I had to sob like a child to make my doc realize that I really felt sick! My vision is blurred, my hair is thinning, I loose my balance, I'm always tired, my skin on my right leg feels like it's burned....but that comes and goes. He finally did a bunch of bloodwork. He called me and said that one of my tests results was quite alarming (nothing usually alarms him!) he said that my TSH level for my thyroid was under .01. He told me that that meant that I had hyperthyroidism. He is sending me for the nuclear/iodine uptake test. This is what I'm scared about. Does that test kill the thyroid? I've read that I could have Thyroiditis, and that it could resolve itself in a couple of months by itself. Can anyone give me any input? PLEASE????
