Studying up on an aspect of perturbation theory

[Mentat]

I was studying up on an aspect of perturbation theory, and I must have strained something (there's something about Hilbert spaces that I just can't get my head around...sorry, bad joke), because I have a really bad headache now.

I was wondering what a headache is, and how we get them. I know we can't feel our brains, so I was wondering why it is that the pain feels like it's inside my head.

Any input or link would be appreciated.

Thanks, Moonbear!

One question: How could my focusing on a math problem (for example) have any causal relation with my headache (or, could it?)?

A few ways I can think of off the top of my head (groan...no pun intended). It could be eyestrain from reading too long, muscle tension from getting mildly stressed that you can't wrap your head around that difficult problem, or something like neck or back strain from just sitting with your head bent over the desk too long. Or all three!

Hope your head feels better.

mentat, i suffered for years with headaches, to a point where i would avoid reading. i just got a pair of reading glasses, and it is so much more fun to read and i have no more headaches! if you are studious and do a lot of reading, i would think about having your eyes checked.

Actually, I already wear glasses, but I'm way over-due for a new prescription.

that might be part of the problem mentat...good luck in getting them checked.

Yep, needing glasses or wearing the wrong prescription can cause headaches. When children get a lot of headaches, usually the first thing they check is their eyesight.
