I have a swolen optic nerve in my left eye, but it causes no problems. I used to have to go to the hospital for check ups every few months for about 4 years before they realised it wasnt doing anything, so now i havnt got to worry about it. I had scans and had a dye put in my blood so they could see all that shizzle, i cant think what it's called. I pissed orange for a day and a half - but no one told me i'd be pissing it out untill i did. I thought i was dying LOL.
