I get ringing in my ears, though I don't know why & mine doesnt correspond with how I sleep and it happens during the day, too. HOwever, I have had neck & shoulder pains with spasms and found a cervical pillow gave me alot of relief. Now I cannot sleep without it. I use while sleeping on my back and my sides. The one I have is one of those horseshoe shaped ones, but there are many different kinds on the market. It helps keep my spine straight while sleeping, rather than my head being lower or higher than the rest of me.
