Why did clear mucus come out of my anus when that day i took heart-burn med & got diarrhea, i used toilet sprayer to clean myself but i took long doing it so don't know if water got trapped in anus canal & i was on infection med too?

Toilet spray water is unlikely to get inside your anus, even it it did, it would not do any harm. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV vaccine. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-preventio
