I have the same problem. I get headaches on the left side above and behind my eye. I've had migraines for a while, and it's a different kind of headache. I had a CT scan which was negative. I went to a neurologist, and he said it's normal to change headache patterns, and I was prescribed Topamax. But he checked my eyes out, he said I could have had an eye problem, but didn't.
its either because u need glasses and are straining your eyes too much , or a migraine. ways to get rid of migraines is 1) caffeine 2) cold shower 3) nap, keep eyes close because this sometimes makes it worse
if they persist i would go to a doctor they will probably check your eyesight and figure out what may be causing them. i get migraines daily and they did this with me and figured out it was stress related.
if it is migraines they will probably recommend you take excedrine, or tylenol.. if this does not work they can prescribe you something stronger.
