Something stuck in throat , like there is scratch in throat , a feeling of obstruction , no cough , no pain , no acidity type feeling?

Tonsil stone?: A frequent cause for this type of symptom is a collection of debris or food particles in the small pockets of the tonsils. These are known as tonsil stones and can be associated with bad breathe. If there is a stone present, then try to dislodge it with a q-tip or water pick. These are not dangerous, but more of a nuisance. If the symptom persists, then it would be best to consult and ENT doc.
