strange new head symptom-

For the last three days I have had this new symptom. It feels as if someone is tapping on the back of my head with their hand. It only last for a few minutes, but this is new. Anyone experiece this weird tapping?  Thanks  D

 Yes,I think most likely, spasm or twitching. But I thought it was in a strange place this time. Ive had the finger twitching as I posted before but this in the head is very strange feeling and was wondering if anyone had the same.   D

I've had the sensation of something crawling in my hair, right at the back of my head. I too chalked it up to muscle spasm, since I get them everywhere else. GW

Once in a while I would get a feeling almost like bubbles moving under my skin. I have felt that in places on my scalp, and on the side of my leg where I have a few varicose veins, maybe other places too but the scalp was the most recent. It wasn't pain, and only lasted a few seconds, so I wondered about it, but didn't think too much about it until you mentioned your tapping.
