Hi i have had a lump behind my left ear for almost 10 months now. When i first felt it that 10 months ago... i went to the dermatologist and they had no concerns with a visual check but never took a biopsy. Now its become a huge irritation, very itchy to the point where i would make it bleed if i didnt have such self control stopping me. If its changing from something that hadnt bothered me in the past, to something that is, could it be changing into something of a health concern? Should i bpther getting it looked at once more? If no, then is there something that would ease the itch?
