[|Human|] Hi about 4 months ago i found a lump at the back of my head, i told my doctor he said ita likely nothing and if still there next year hell recheck. However it disappeared after a little while and has now reappear today, a little sore to the touch and abit squishy. About the size of a ping pong ball, im quite worried as ive been having speech problems lately even though i know the word. I told my doctor and he says its nothing. Should i be worried and beg for a second opinion?
[|AI|]  Hello, Thanks for the query to Chat Doctor. Forum. The swelling on the back of head and reappear and now sore to touch as may be, 1 Desmond cyst, 2 Sebaceous cyst Can be confirmed by physical examination by another doctor and get his opinion (2nd). Cause of concern is that this time reoccurs, painful, if your speech problem is related to this tumor then consult at once and get an M R I according to your consultant. If sebaceous or Desmond get its surgery (excision). Hope I have answered your question. If further any question, I will help. Good luck.
