I keep getting dizzy and nauseas, along w/ alternating violent chills and sweating. I have been in bed for a month, but the first 2 weeks my thyroid had dropped low again, which was ovelapped w/ a sinus infection. Now that my synthroid dose has been raised and my sinuses are cleared up I'm still exhausted, I'm having bad dreams, and my body keeps "dropping?" I actually fell over yesterday and brought the keyoard/stand and stool down with me. Is there anything I can do to combat this? Any help, suggestions, ideas, anything you've got will be GREATLY appreciated!!
