Jess -  I'm no doctor but it's true that most people don't get head pain from sleeping.  I have had those kinds of headaches, too.  I usually get them when I have messed up my sleeping pattern somehow.  For instance, I will get those headaches if I get too much sleep or not enough.  I try to go to bed at the same time and get up at the same time, even on the weekends.  You also might consider that you are allergic to something in your bedroom.  You could try replacing your pillows and comforter with hypo-allergenic materials.  Also, you could make sure you are not elevating your head  too much when you sleep.  Do you have pets that sleep in your bedroom?  Mine do and I can't bear to kick them out, even though they snore, shed copious amounts of hair,  scratch themselves at length and jingle their collars, emit hideous smells from time to time (have they been drinking from a septic tank? or what?) and otherwise make themselves at home.   My doctor did once suggest I kick them out.   But I haven't.
