Thanks for writing to H.C.M. for your query.
I have gone through your clinical history and I have co-related the endoscopic findings. After considering the every aspect the possibilities of glob in throat are-
(1) Globus hystericus
.(Gastro esophageal reflex disorder
(3) LPR. (Laryngo pharyngeal reflex
These are to be further worked out by good clinician to find out the correct disease, which can be managed later.
Wishing you an speedy recovery.
