Got one for the first time a few months ago. Was bloodshot for 2 weeks. Started using some Optex or whatever, went away, came back about a week later, still felt perfectly normal. A week later went to the doctor, they couldn't see anything, gave me some eyedrops. They eventually made it go away, I stopped using them a bit early, it started coming back. Used eyedrops again, went away. Appeared briefly for a day last week.
