I had thyroid surgery four months ago. There was no cancer and my thyroid levels are normal with no supplemental meds. My problem is I have had so much trouble with dizziness and heart palps when I go to bed at night. They are ten times worse around my period. I've read a lot of literature that suggests I am peri-menopause (age 38). Could surgery have spun my other hormones (adrenals, ovaries, pituitary, etc) out of line? Some have suggested my progesterone levels are low. I get dizzy, sore joints, heart palps, etc. I've ruled out MS, autoimmune diseases. Saw a cardiologist and he's following up, but really believes everything is okay and that it may be hormonal. Soem days I get these waves of weakness. It's almost like whatever this is has a switch...some parts of a day I'm great and there are other whole days when I drudge through the day. I am height/weight appropriate and up until my surgery was a 4 day per week exerciser. My primary, though, has been totally clueless. Surely there are other people out there with this. The fatigue, muscle twitches, and other symptoms come and go, but it's starting to wear on me mentally. Anyone have a suggestion on what this is...low/high hormones, etc? Some people have suggested birth control pills, progesterone cream, and hormone level testing. If I do hormone level testing, is saliva or blood more accurate? I am supposed to see my OB on 2/7. Any insight anyone has for me prior to that date is appreciatd. Thanks!
