For The Past 4 Days I Have Been Having Pain

For the past 4 days I have been having pain right above my left eyebrow and it hurts more if I touch it it actually feel as if there was a bruise there and I was pushing on the bruise but I have none there. I haven't flown recently, haven't had any accidents that would cause this pain. What else can it be? I have been taking Tylenol but that doesn't help most of the time.
