Ear discomfort. But nothing helped.

Three months ago i got my left side wisdom teeth removed...after that i was not able to feel half of my tongue and i heard a sound (sound like purrr kurr) when ever i touched my  left ear or i blowed my nose or did some thing which requires giving presure like doing latrine..but doctor told me it is mild paresthesia it will resolve...My tongue got better but i still hear this (purr kurr like sound) in my left ear when ever i touch my  left ear or i blow my nose or did some thing which requires giving presure like doing latrine or when i blow my nose in wards (Sucking in air from nose)...This sounds goes away when i pop my ear but again comes back...I took anti allergic ,nasal spray and steam inhalation but nothing helped...
