I've been experience a periodic spiderweb-like tingling in the top right back of my head for a while now, it used to be not so often and now for about 2 weeks it's been almost everyday, sometimes more. I would've shrugged it off as nothing but now the tingling is just getting annoying. Does anybody know what this might be? (I have mild scoliosis, it's not a huge issue because I'm getting treatment for it but could this be contributing to the tingles?)
