Dear doctors, Two months back I had lot throat infection. Since then consulted few doctors and got 3-4 courses of different antibiotics. Throat Infection got cleared but had little tightness in swallowing saliva. I got my Blood test done for infection and all tests were fine and normal. But the problem I still face is, whenever I sit in AC room or have certain food, I start feeling Throat Heaviness while swallowing saliva. No cold, cough, flu , acidity nothing. It gets better after rest next day. What is happening and why? Thank you for your kind replies in advance.
