That is funny to have pink eye so many times in the last few months.....you probably need to talk to your doctor about it.
Do you use a product called Reun with moisture loc? There are problems associated with that.

You might do a search on chronic eye infections and see if anything looks like what you have. I hope you get to feeling better. Hugs!!
