Hello. I am a paranoid 26 year old male. I see this strange flashes in my eyes, and I am nervous that they may be due to optic neuritis. I don't have color loss, no vision acuity loss, I do have a mild dull pain in my eye....but it goes away when I don't think about. I have seen an eye doctor and he said that my nerve is fine, and that i might simply be seeing entopic phenomenon. I do not think that i have other ms symptoms, but often times my panic and anxiety take over and I am sure that i do have them. I have been seeing these flashes for over a month now, with no other vision disturbances. Does this sound like something that might be associated with NO? Also, I do not get these with movement or noise, they seem to arise out of nowhere. Thanks, and I appreciate your knowledge and desire to help.
