I suffer also from red eyes. Blood Shot. I look back on some pics and realize that i have had these red eyes for approx 3 years. I also suffer from maxillary sinus cysts which can play a roll in the red eye
Apparently I have struggling with my red eyes for like the 2-3 months now worse than ever before. The Rheum has chalked it up to my RA and I have been prescription eye drops for it. I thought it was just allergies, but now I am understanding Lyme better and better these days.
Red, painful eyes was my first symptoms. It lasted for a long time.
Only recently since my Lyme bugs have moved pretty much out of my brain have I been getting bloodshot eyes. They feel a little swollen when it happens, and a little dry, with red veins clear against the white. Sometimes my eyes don't focus properly, but mostly it's just redness that goes away after a while. I have saline solution in little plastic tubes with tops that snap off and use that if my eyes are really annoying me, just for soothing. I don't think it's uncommon, but for a long time it had never happened to me. Perhaps it's just the bugs on vacation, looking for new places to hang.
Mine get reddish round the edges but not the whites, they are dry and itchy all the time, I do get allergies so assumed that was it.
