So I wanted to ask about a particular thing that happens to me usually when I'm feeling overwhelmed or just annoyed by something and it always seems super weird to me.

It feels like there is physically something inside my head that should be taken out. It's not a headache and it doen't hurt at all. It's just annoying, irritating and really really uncomfortable. How I've been describing it to myself is like there is a stick/thorn inside my head. The sensation doesn't really remind me of anything else but if I had to compare it to something then maybe if there was a tiny rock in my shoe that got stuck between my toes or something. It almost feels like a mosquito biting you... When you first see it and it's not that bad at but the more you focus on the mosquito the worse it gets. 

I was just wondering if anyone has ever had the same experience? 

 I'm not even sure if it's anxiety related but it usually happens when there is something bothering me.

Thanks for reading
