Hi, welcome to the forum, the possibilities of such trickling in throat
are Allergic or
seasonal rhinitis, Bacterial pharyngitis or tonsillitis, Sinusitis, Influenza etc. It is very important to point out the source of infection.
This feeling of something there in the throat is known as Globus sensation. This is mainly seen in gastro esophageal reflex disease or hyperplastic tonsil.
You should stop taking spicy food, vinegar, alcohol, cigarette smoking if present.
