Thanks, Peggy and Elizabeth. My sister (the RN) just explained it to me. It is possible to have a higher TSH level but still be normal. It all depends upon what the T3 and T4 are doing. I haven't had mine done in a long time. My mom had thyroid disease, so I've been monitored for it the last 20 years or so. I went through my records this morning that my endo dr. sent me in anticipation of surgery, and my TSH has always been in the 3.5 range. At a minimum, I guess I owe it to myself to get a prescription from my PCP for all three to be redone. Then, I can see what's going on and if I should see the endo dr. (who is now over an hour away from me -- which should be no big deal, but I'm from RI, where anything farther than 20 minutes away requires an overnight bag
). I've always had dry skin and hair, and have always had severe weight issues, but I sleep well at night and am not typically cold. It's definitely a point for follow up.
