Hi. I've Had Ear Problems All My Life, But Recently

Hi. I've had ear problems all my life, but recently I have had problems STRAIT for about 5 months now. I have gone to pediatricians, Med Expresses, and even specialists, who say it is simply tmj and recommended a soft food diet, which I have been following for a few weeks now. This morning I woke up with a painful non moving bump on the bone of my ear, and thought the day it has gotten bigger and more painful. What should I do ?
