Hi Doc,I have a hard lump on top of my skull (I believe it is forward on the parietal bone close to the coronal suture ) It is not painful and appeared in the last 3 months or so.I am 49 years,male,weigh 195 lbs. and am 5'11" tall.I had a head injury when I was 6 years old.Got hit by a car (my babysitter ! ) and bounced down the street.Spent a few days in the hospital then,and have had no lingering after effects.When I press on it,it feels firm and tender,but other than that is not bothering me.Any advice,thanks.Paul in Edmonton,Alberta.
