I can't really help with your specific problem, but I do know a bit about what you're going through as I had unexplained optic neuritis last year, in my left eye. It was in october, and I would say I have just about fully recovered. I say just about because sometimes I still get pain in that eye and i've had a few days where the pain really reminds me of the type of pain when you have on (not intense and more like a pressure). Obviously this causes me panic when I think I may be getting it again as they do test you for ms on a second occurence in my health care area.
I have my last (hopefully) appointment mid july at the opthalmologist in the hospital, and I hope to be 'signed off' that day.
I can also relate to the sinusitis thing, as that's what the hospital tried to tell me I may have, I went to the doctor who gave me antibiotics just in case, but he was reluctant to believe it was the cause - especially since I wansn't experiencing the type of pain you would get with sinusitis.
Mine has been put down to a virus I think, and I just have to hope there's no recurrence of it.
Hope you are feeling better soon. :)
