Swallowing Difficulty. Antibiotics.

I am difficulty swallowing food, and it feels something is stuck in the throat all the time.I had consulted a doctor and he said that i have acute tonsillitis. But, I am not sure about the it as swallowing difficuties appeared immediately after i was stretching my neck.Also i dont have any other tonsillitis related symptom apart from swollen tonsils and difficulty in swallowing.There is no pain, sore throat etc. Please suggest if there is a possibility that I might have injured my self while stretching, Because had tonsillitis been a problem i think swallowing problem would have appeared gradually not immediately plus there is no other problem apart from swallowing difficulty. It has been a week amd no improvement in swallowing. I am taking antibiotics.
