Last week, I was sent to the eye clinic because I had eye pain and lost vision in my left eye. I was diagnosed with optical neuritis. The same day I found out I was pregnant after TTC for a number of years. I have been told I will need to go for an MRI to assess the damage of the brain and spinal cord, with possibility of MS. I am worried sick. I have stupidly devoured the internet looking at this and haven't slept in over a week. Has anyone had ON before? Was this an isolated incident or did it lead to a diagnosis of MS? Any experiences would be appreciated.
