I have had a lump on the top center part of my head for around 7 months now that hurts very much when touched,it seems to have spread out on both sides like a tree branch.I suffer from severe headaches and constant pressure.I have gone to a Dr. and he said it was a cyst without even looking at it.I have also been to the ER and they took an x-ray and said that they couldn't find anything.I had a very bad fall around 4 years ago.I fell backward and hit my head first,was knocked out and when I came to,I was totally paralyzed,I couldn't even talk.The only thing I was able to do was move my eyes.Around 5 min.afterward I was able to get up.I believe that I had a concussion because I was seeing spots,flashes,and different colors for days.I feel this may play a big part in the lump.
