Hello, my name is Bec, i'm 16 years old and a week + ago i found a lump behind my left ear on the cartilage, at first it was tiny like a pimple now it is about 1cm and growing slowly but is very painful. it has been causing me many throbbing migraines the past few days, i cannot sleep on my left side at all without discomfort and pain. it is painful to touch and if touched too hard brings me to tears. i have been feeling exhausted also, my family have a strong history of cancers and non-hodgkins lymphoma. i went to the doctor and they wanted to ultra sound it but they said it would be too small to pick up, they have already confirmed it is nothing to do with the lymph nodes. please help i'm terrified?!?!?!
