I have never had problems before, although I always knew four of my relatives have hyperthyroidism. I'm 18. One day I suddenly felt my heart race and I began to sweat, and I went to the toilet 3-4 times that night, my metabolism was skyrocketing. I performed all the tests for the heart but they all came back normal except the high rate. I first performed a blood test the next day, and it was 26, with a range of 11-24 in that laboratory.
The symptoms lasted for 1 month, then they disappeared and now my latest blood test shows 15, with a range of 11-24 so it's normal. However, the only thing tha that has not disappeared is the racing heart, which is at like 90 bpm or more.
Any thoughts? Was it a thyroid storm? Was it thyroid at all?
