Quivering in throat / esophagus/neck scares me

[Raekar]

I have this quivering feeling or spasm feeling near my esophagus and sternum.
I also get it in the back of my head with pressure. I sometimes get dizzy but dont know if its related or just anxiety which makes me panic and get dizzy when I get that feeling. Please help. O and sometimes I feel very hoarse in my throat almost like Im having trouble talking. Like weak in the throat. Sometimes these symptoms happen all together and sometimes separate. Helpppp!!!
