My eye is swollen and bright red. There is extreme pain under my brow bone. this has been going on for weeks. it comes and goes so randomly. I have also been seeing little flashes of light lately. I have had an MRI done, and topography of my eye along with other eye exams. My retina is fine. I had an allergic reaction under my eyelid which was treated but the other issues are still present. No one has any solutions for me. During the MRI they found I had sinusitis but that was also treated with a nasal spray and the eye problem continues. HELP.
