I have this sensation of something in my throat, I get spams on my neck and sometimes the feeling of being choked. I have a sensation in the back of my mouth like it is fuzzy or something stuck. I have been treated for sinus infection thrush and had a CAT of the throat and also the scope down my nose. They say there is nothing there. They put me on axiety medication and not the past week my tongue feels swollen and bad taste in my mouth. Please help...
