For the last 9 or so months I have felt something pressing in my throat. It is right around my adams apple. I've had two doctors tell be my thyroid is slighty enlarged. I've had 2 thyroid tests down this year and my thryoid was on the higher end of normal. Not high enough to take medication. I have had anxiety. I went to an action movie and my heart was racing, I was so tense. I'm having trouble winding down to sleep. Today I had to perform in my music class in front of my pears and I felt my heart racing and I couldn't stop shaking. It's normal for me to be a little nervous, but not to this extent. Something feels like it's stuck in my throat. It affects my singing too (i think it may be rubbing on the vocal chord). The uncontrollable heart racing is scary. Any suggestions on what I should do?
