trouble swallowing solid foods

i'm 19 years old and i have trouble swallowing solid foods. this started for me about 10 days ago when i was eating my favourite candy a reeses. i began to choke because it felt as if a lump were in my throat and ever since then i've not been able to eat it constantly feels as if something is there like a mucus or something food gets stuck when i swallow i've been to the e.r the clinic which referred me over to a GI clinic which then gave me a barium swallow test that showed nothing. also i have this tooth that only hurts when i chew on it could this somehow be linked to my swallowing problem? i've also been reading up on swollen lymph nodes is ti possible that i have some in my throat? yes, my tonsils and adenoids have been removed years ago also there is no pain when swallowing. only complications
