After reading your first post again three times and then your last post a second time, I am wondering if your heart rate has nothing to do with your thyroid.
If your TSH is 6.2, that is a little hypo, but not much. If your T3 and T4 were very close to normal ranges, that is not very hypo. You are not very specific, so that is a lot of guessing. I would want the test results. You can get a copy.
An antibody test (for both Hashimoto's and Grave's disease) would be a good idea, and also TSH and T3 and T4 if it has been a few weeks. Then talk to your GP about whether Synthroid would be apropriate if you are not already taking it.
I don't know what POTS is, but I read a few sippets on IST and that sounds a lot like what you are going through. Has anyone suggested tests for that?
A Pheochromocytoma could cause those symptoms also. That would require the services of an Endocrinologist as well as any thyroid issues other than basic hypothroidism with no antibodies. Have your GP run some tests and mention possible adrenal problems. He might want to run some preliminary tests for that as well.
Process of elimination. A good GP will run the right tests till he/she finds an answer and then point you toward a specialist. If your GP won't run test after test till she finds an answer, find another GP.
Best of luck.
I cant even walk to my car without hy heart rate going to 150 and feeling like im going to pass out or just even walking to go to the bathroom not to mention being home with a 4 year old who doesnt understand why mommy cant go run around and play or go to the park and play with him and a 9 month old who just to get up and get a bottle leaves me out of breath and exhausted! Is rather have something that with medication I would feel better not this my heart rate is ALWAYS high its not an occasional thing its 24 hours a day I know lots of people that have hypo and are fine but I have read alot of stories on here where people go through hell becuase of thier thyroid, so I know its different for everyone but for me this has taken away so many things that I love in life, im wondering how im going to take my kids trick or treating things that people with hypo im sure dont have to wonder about.
If the Good Lord told me I could have a resting heart rate of 60 (instead of often 100+) or be free of Hashis, I'd easily choose to be free of Hashis, hands down. Heart rates wax and wane and the rhythm itself isn't dangerous if it's sinus rhythm.
If you had the sympyoms of true hypothyroidism you'd understand...
Good luck with your appointments
Frankly, likely having both, I'd much rathe have IST than thyroid disese.
I do NOT have Hashimoto's (meaning that I do not have thyroidperoxidase antibodies), but I definitely have hypothyroidism. A rapid heart rate is not on the standard list of symptoms, but it has been one of my body's favorite ways to tell me that my thyroid gland was not doing a fully competent job. You mentioned having a doctor's appointment in mid-September. I hope it is with an endocrinologist. I think there is far too much to know about the endocrine system, and problems with it are far too complex, for a general practice doctor to be messing around with hypothyroidism. My GP agrees!
Thanks for your post ...I can't imagine 120, I feel like crapola at 25...your story is the same as mine, but I had RAI to stop the thyroid from dumping, so far it's been ok haven't had any major hyper issues in 3 months, my blood sugar has returned to normal too. And my heart rate hasn' went over 80....almost feel normal...almost ...still alot of pain, and some brain fogs.
