I have a ? about my TSH levels that vary from 0.1 to 2.90 with a normal T3 & T4 for the past 7 yrs. Ive seen many Drs that say your tests are normal. one time TSH was low but had a high prolactin level. Did a MRI checked for pitutary tumor found nothing. I have alot of hyperthyroid symptoms CP, palpatations,SOB, sweating, heat intolerence etc. but nobody seems to think its a problem. The palpatations have gotten worse & flushing. Any suggestions on what to do next. Thank You!
