i think ive got hyperthyroidism as my dad also got it, and i will have my blood tested next week to confirm it. My heart beats very fast at about 90 beats/min, and at the same time, i can feel my pulse on the right side of my head above the ear but not the left side. Occasionally, it really hurts me so im afraid i would get stroke. Can you tell me whats going on in my head. Thanks!
