I have had optic neuritis multiple times and the pain I experienced included a burning sensation, sometimes my eye would throb, the pain felt like it was behind, below, in the
eye, etc. Your doctor can look into your
eye and tell you if the nerve is
swollen. If the nerve is swollen they usually prescribe steroids. If you would like to talk in more detail about this problem w/someone who has dealt with MS since 1995...send me a note. I would love to talk with you.
