I am guessing perhaps tension headaches, although it could be any variation of headaches, really. I hope the dr can tell you more! See the link below re: tension headaches (especially the info. for symptoms and treatments):

I have had headaches since I was 7...well that was when I started getting migraines and I think I started getting tension headaches when I was a teenager. I take Topamax to prevent them and it does a great job for me.

I also use ice on my forehead (carefully, eek! 20 minutes on and off) if I feel "headachey" and a moist heating pad on my neck and upper back (I have very tight muscles)...both have helped so much!
