Hi again, I hope you don't mind me asking another question, do you have any other allergies? Like seasonal, to animals or food? You've mentioned you had burning eyes after working with mulch, my daughter had burning eyes after swimming in a pool. She had the burning sensation many times before so we didn't pay attention to it anymore. But she has other allergies and that could just make her more sensitive. Other people have burning eyes after swimming in the pool but they don't develop optic neuritis. I am trying to find a connection between the two of you and so far I only found the burning eyes. Hope you are feeling better.
