Constant Headache

Since spring arrived, I have had a continuous headache just above my eyes. I have tried all over the counter meds and have now been put on Alagesic. Just wondering if anyone else has had aches like this and what was your remedy. I have been told they could be summer headaches that could be caused from glare, humidity and dehydration.

The only thing that remotely works for me is Tylenol and 2 to 3 hours later Motrin
