m 23 and ive been smoking for 3 years now since i was 20 and

it feels like something is in my lower throat and its a little ichy
ive been hacking up alot of mucus
and ive stopped smoking since 4 days ago once i felt like there was something in there
and checked for a lump AND NO lump in my throat
i dont know if its alot of mucus or some food particle or something its starting to scare me cause im having anxiety attacks again
my throat doesnt hurt it just feels like something in the inside of my lower neck and its bothering me
is it throat cancer? or what

i did hack up something yesturday that was little and yellowish my throat did fell better but now i got that feeling again

seem to have a acute sore throat pretty often.
i talked to my Ear nose & throat doctor and he said that he would take my tonsils out for me or he could put my on a long regimen of antibiotics. I wasn’t thrilled with the idea so i said i would think about it.
I was reading about how your tonsils and ears are connected, and im starting to reconsider having them out.
Every time i chew gum it feels like i have fluid in my ear, also i feel like i don’t hear as well as i should…..Im 16.
Could this all be connected?
and if i get them out does your hearing increase and will it most likely fix the fluid in ear problem?

also im a singer…….it wont change my voice right?
