I have a headache that came on about 3 months ago. There is a heaviness in the corner of the right eye and underneath and pain above eyebrow that extends straight up to the top of my head. My right upper eye lid also twitches. I have a lot of problems with nasal congestion and ear fullness. My vision gets sort of blurry in the right eye as well with a feeling of pressure behind it. Went to the eye doctor twice and they said my eye looked fine. They checked the pressure and that was fine too. My sinuses are always clogged on one side or the other but not much will blow out. What I can get out is always clear with no color. The thing that makes me wonder if it could even be a sinus headache is that the pain goes from my eyebrow straight up to the top of my head? What could be causing this headache?
