It's been two years and my hearing in right ear comes and goes, right ear is completely deaf for 3 days then in two-three days periods it starts to recover until it's back to normal that makes it six days. In the beginning time period was about 1-two months between hearing loss attacks but since last few months time period has been reduced to one week to be exact and in perfect timing it occurs and it's perfectly fine after 5 to six days. I've gone through steriods treatment and what not but steroids only reduced time gap.
