I was just feeling better and happy for once and I scratch te top of my head and there's a great big wide bump around the middle back of the top of my head and a similar one nearer the front, in the middle and, the middle. This was a similar worry not long ago. I don't remember banging my head there and it doesn't hurt but is it me or is it slightly more numb than the rest of my head? I can't stand it why do I have to be like this???:( What's everyone else's heads like? Are these bumps in fact normal and I've just never noticed them before? I have a cold that's clearing up - would that be a cause maybe?
