I sometimes wake up in the middle of the night when I am scratching my scalp - some places are itchy, and while I avoid touching my head during the day, I tend to do it unconsciously (and quite aggressively, I am afraid, pressing my nails on the scalp) when I sleep.

When this happens I wake up with a more intense headache and I have trouble sleeping again. This is at least partially an anxiety reaction, but could the scratching be a problem in itself? I try not to worry about it and think that this should not transmit a significant force to the brain, but I am still nervous about it. I am wondering whether I should sleep with gloves to avoid that. Any thought would be appreciated, thanks.
