Can intrusive thoughts cause headaches?

I've been struggling with Tocd since august of last year and one thing I tend to notice is that with these thoughts comes a headache. Like often times I'll be thinking about the subject for so long I'll end up developing a dull pain in the left side of my head. Though It makes me wonder if other's have gone through this exact thing as well and if so, how do you deal with it?

I can believe that a stress headache would be a possibility.

I have TOCD too, and this has been happening to me as well...
