Has anyone had persistent headaches that just won't go away from meds? I get one about every other day. I'm not talking about minor ones either, but pain bordering on migraine territory. It seems like no amount of headache medication or water gets rid of them. Does anyone have any suggestions? I know I spend too much time on the computer because of work (and PC), but they start about an hour after I take meds in the morning. Please help!
