I was treated for trich & a UTI about a week ago. 2000 Flagyl and a little bag of amoxicillin. I now have lime green clumpy discharge. What is it?

Vaginal discharge. Sounds like lime green clumpy discharge of unknown etiology. All kidding aside, this can only be accurately diagnosed after being seen and possibly cultured. There are several bacteria, including pseudomonas (which is resistant to what you have taken) that can produce secondary overgrowth infections. In order to clear it up it may have to be cultured and examined under a microscope. Good luck.
