It’s been almost 18 months since it started. Every month, I get a right ear pain followed by shoulder pain that goes all the way down to my hand. Recently I’ve noticed a lump in my neck right on my ear line under my jaw, under the skin, and since it’s in the same side I feel the pain I’m not sure if it’s related. It usually goes away and comes back. I’ve taken muscle relaxants and it helped, but regular painkillers don’t. What could it be?
