This started yesterday morning when I woke up with slight discomfort mostly if I touched it on the top of my ear and behind the top part of my ear and also scalp of head was a little sore as well...then later that evening as I began to rub my ear because behind it was beginning to itch a little and was feeling a bit warm I noticed that there had developed a few small size bumps there ...today its itching and still feeling a bit warm....more bumps have formed..and still hurts a little when i touch it just wondering what this could be or be related to...just to mention I had two teethe pull the left side very back a d was taking amoxiin to prevent infection...took them all as of three or four days ago...can you help?
