hi, I had a lingual tonsillectomy over a year ago. Every since the surgery, I feel like I have something stuck in my throat and I will have occasional coughing fits, where the back of my throat gets so irritated and I end up vomitting It usually happens in the middle of the night, but has happened during the day as well. I have seen my ENT for follow up visits, but he seems to think it is nothing physical, which is upsetting. What do you think it could be?
