My thyroid gland

hello guys, i have been diagnose hyperthyroid for last 2 month, and now my thyroid level TSH ,T4 & T3 , all are normal , but now i feel something stuck on my neck, especially when i was exhaling, sometimes i feel like it was moving upwards n make me feel scared, help meee, im scared if i cant breath but act i can breath normally, iwant to know act, if thyroid gland can contract with thyroid meds or not?

I think I would go back to the Endocrinologist and find out what is going on. You may need to get an ultrasound of your neck, and some lab work done again to find out if their has been a change. This does happen to a lot of people. Call your doc and ask for an appointment to discuss this. It is not normal.
