Well the ophthalmologist looked at my eyes and said it wasn't ON - I wasn't expecting it to be as my colour vision felt normal but it was nice to have the reassurance.
Going to see my dentist this thursday if I can just in case it's related to some work I had done on my teeth over two weeks ago. If not I can't think what else it could be aside from TN - whatever is causing my eye pain it's bloody painful. I don't feel like doing anything this evenng - hope I'm ok to make work tomorrow. I've managed to struggle along with all my symptoms up to now but I think if my head/eye are killing like this tomorrow I won't be in a state to work :-(
