what is bilateral mastoid sclerosis? I have recently had a ct of my brain and the findings were that My mastoids appear clerotic bilaterally and I dont understand what this is. I have a pain in my ear that wont go away, its more behind the ear, but hurts everywhere ingeneral. Apart from these findings, the ct results say that everything else is normal. My pain wont go away, how is it treated? thank you. Sincerely Amelia
