Green poo suggests a bacterial infection (or have you been taking a supplement like Chlorella?), so you may need to take Antibiotics .
I took Antibiotics for a staph infection. My doctor gave me antibiotic-resistant probiotics. They seemed helpful since I didn't have an increase in yeast symptoms after finishing with the Antibiotics . I was following a strict anti-yeast diet at the same time and followed the antibiotics up with a couple of weeks with an yeast killer, so that probably helped.
