Hi, I had a lump a few years ago behind my ear that was checked and I was told it was a cyst fast forward to now and I've noticed a smaller more painful lump underneath the cyst, it feels hard, boney and tender, i cant tell if its a seperate lump or part of the original one above it. I have been reffered for an ultrasound the doctor said she doesnt think its lymph nodes, it could be cysts or possible mastoiditis?but I was wondering has anyone else had this and what the outcome was? Thank you.
