Infelxible scalp - cause and effect ?

[stilltrying]

My scalp used to be very tight and unnmoveable - I couldnt pinch it all. It felt like there was a buildup underneath it - like liquid or scar tisue. Does anyone know what it actually is ?

Aw comeon guys ! At least say if you know what I'm talking about ? Surely you have had that feeling when you squeeze your scalp. Or is it only me that didnt used to be able to pinch my scalp ?
