How long have you had this? Could you have an infection unrelated to lyme?
The reason I ask is that two people in my group of 8 friends who get together once a month had an eye infection that's going around right now. They hadn't seen each other so didn't get it from each other. One had a very swollen eyelid.
I guess it can be serious and affect vision if not treated. They were both on drops.
Also, once on the drops it's not contagious.
Yours may be only lyme related though,
