Sometimes I have eye pain in, around and/or behind eye. Comes & goes and effects both eyes. My vision doesn't change. Worried about Optic Neuritis.

Just curious...: Why you are concerned specifically about optic neuritis? A female in her mid twenties might worry about this, for example, if there is a family history of MS or another CNS disorder.

Pain should be evaluated by your PCP. ...Read more

Make sure you tell your ophthalmologist about any other medical conditions. ...Read more
