I am 28 yr old male. i usually get throat infections very often and take antibiotics ( cefakind, pulmocef or clavam etc. ) as per doctor advice. Also i have high odour perfume allergy , whenever i smell high odour perfume, immediately my food pipe shrinks, so i usually need to take hot water to make the food pipe expand. Always feel there is something near my throat. Also when i drink water, some times i can feel the water goes down very slowly. I can feel the water from the mouth takes one or two seconds to travel the pipe. What could be the reason, can you pls let me know what are the next steps i should do
