I was just looking for my physician s card to call him because I am so miserable. When I found it I saw that I had written down my symptoms on the back of the card for my appt which was 2-18-10! So I know this has been going on well over a year. Every day, at approx Noon & 6:00pm I am racked with horrible chills - like ice water running thru my veins. It doesn t sound like a big deal I guess but it still catches me by surprise & it s always the same time when I look at the clock. I m thinking that it might give a clue as to what is wrong with me but nobody seems to know what that is. I have 1 other symptom that does not go away. I am 60 yr old woman & I hoped as I got older that the problem of night sweats would decrease....they started around 12 years ago & to be honest they have gotten progressively worse. My Dr does not think it is related to menapause for this reason. Every single night it s the same thing...I wake every 2-3 hrs completely soaked. Bed is wet, pillow is wet, I feel miserable. I am on thyroid medicine as I had 1 lobe removed 9 years ago. The dosage was high but has been dropped over the years. Now I take 100mcg along with cytomel. Just 3 years ago I was taking 175mcg with cytomel. Anyway, all the blood work shows my thyroid levels are fine. I just can t understand how I could feel so terrible & have such perfect bloodwork. Finally, to make my life totally miserable I have gained around 15 lbs in the last 3 months. Up till that time my weight was always fairly consistent. Any suggestions you might have would be greatly appreciated. Isn t it possible that although my levels appear to be in the normal range that it might not be normal for me? Help!
