For more than two years, I have been experiencing pain behind my left ear. Find the middle of your left ear, then move to behind your ear, in the crevice between your ear and your head - that's where the pain is. There is usually a little bump which is so painful to touch. I cannot sleep on my left side because my entire ear hurts and I think the sensitivity and pain is worse when I am under stress.
I have been to 5 doctors or so and it's not TMJ and I don't have any inflammatory issues and it's not a skin disorder, so I do not know what else I can do to cure this.
