Im feeling a vibration or drum like sound in my right ear from 15 days but it's not continuous.I also feel a pressure and muffed sound in my ear only at night while I sleep.i can't feel it during day time may be due to surrounding noise.actually I can't describe how I feel a pressure with a sound but not like the vibration or drum like.I am very sensitive to cold means if I get in contact with cold air or I spend lot of time in open air or if I sleep by opening my window open then I will hv sore throat or cold or may b headache like this.Even I am not feeling hot of summer as much as my surroundings people are feeling.i also have ear pain nd I feel heaviness in my ear while I bent down to do something.Before two year a bug has entery to my ear while sleeping and had cut my inner so much that blood was coming out.but after the removal of the bug my ear was normal and I eat some medicines for and it was normal.This is all about my ear history.please help me out.i m really worried.
