Thanks for writing to H.C.M. for your query.
I have gone through your query regarding throat problem of your son persisting for last two weeks, he feels choking
in throat during swallowing while his X-Ray of neck is normal.
Considering your complaints and radiological findings ((normal), I would like to tell you to please get examined your son by an ENT doctor and if he suggest than go for Direct Laryngoscopy
to find out the real facts.
