I am a 37 yr old and have a lump on the back of my neck that used to be small and has grown large and is red and hurts.  The dermatologist didnt want to remove it when it was small stating it would give me a scar and now it grew alot bigger.  What could this be?
Hi, This could possibly be a sebaceous cyst which has enlarged and become inflamed. This is not serious but if it is causing you a problem it may be worth considering surgery to have it removed.  Chat Doctor.
