I don't feel good. my poop is completely liquid with a green tint. i feel like i may throw up. can't stop pooping. some lower stomach pain. didnt eat any bad or expired food. had food poisoning a few weeks ago. butt also hurts from wiping?

The combination of diarrhea plus "don't feel good" (nausea? poor appetiite? abdominal discomfort) suggests viral infection (gastroenteritis, often wrongly called "stomach flu"), perhaps caused by norovirus or similar virus. See a doctor if symptoms are severe or if they don't improve after a few days. Good luck.

You may take PeptoBismol or Imodium. If that does not relieve the symptoms in a day or so, it would be prudent to see a doctor. Drink enough water/juice so that urine is mostly colorless, to ensure hydration.
