instruction: hi doctor my 10 year old daughter had an appendectomy two days back she was in horrible pain after that they wished to send her home but since the pain could not be controlled with tylenol or ibuprofen they decided to keep her in hospital then the next morning she had bad diarrhea she went around 10 times in two hours it concerned me but they informed me that the diarrhea is normal her pain was still pretty bad so they finally decided to try something stronger that we could take her home it did work for three hours and they sent her home by the time we got home she was in horrible pain she was crying most of the night until falling asleep yesterday I noticed a lump on her back that was warm to touch and when I touched it she said that lump is the reason for her pain and it hurts her really bad as I was concerned I called her doctor but they said that they have no idea what I was talking about and they would like to check her in er the next day I know as a parent we over analyze everything I did not to take her to the er because of a muscle strain also I do not want to over look something that could make her worse what could the lump be should I be concerned she still has fever and pain please help
