ringing in my left ear since i had the flu over a week ago when will it go away I had the flu about 2 weeks ago. Since then, my head has been congested, causing my left ear to get stopped up. Now, a couple of days ago I noticed a constant ringing in my ears,mostly on the left side. It is more noticeable when I am trying to go to sleep,or when everything is quiet. How long will this last? It is super annoying!
