Is there a OTC pain medication that's safe to take daily?

I have severe allergies that cause migraines. I'm on a whole host of allergy medications, but most days it's not enough to keep the pain at bay. It's interfering with my life, and I see the doctor several times a month (will be going to her next week actually). I even got a steroid shot to help dull the symptoms. I've found that taking pain medication when the pain first starts helps keep it in check. I've been taking one Exedrine tablet (250 mg asprin and 250 mg acedomenophen/tylenol) a day and it helps a lot. I don't generally drink (the occasional glass of wine when guests are over) and the only other medications I'm on are just antihistamines. Is it okay to keep doing this through the allergy season? Or is it bad for my body?
