Vibrating sensation in my ear. Help me.

I have allergic rhinitis, and due to continuous cold I had eustachian tube block and retracted ear drum so had something like dapping sound in my ear, so consulted doctor , who gave me a nasal spray and some medications for allergy. I'm on it fr 1 month, from 8december, on 31 December I started feeling vibrating sounds in my ear which was discontinuous at starting and would stop if I hear any external sounds, but now it became continuous and I have it in both the ears which sometimes radiate to head. It is disturbing my day to day activities and I'm not getting proper sleep because of this. I visited a ent doctor who proscribed me otocap and hi-folate. In on it from 2 days. But nothing has changed. I'm so confused. So I request u to help me .
