Well, I have a different opinion to some degree. How did this happen and do you know the person you got the poop from? It makes a difference because if you don't know who it was then I would see a doctor but if you do know them well (family member or spouse) and know they have no illnesses (no HIV, no hepatitis, no helicobacter pyloris, no clostridium difficile, no viruses etc nothing else, ) then just injesting poop itself will not cause illness as gross as it seems. They actually use human feces from healthy relatives for a stool transplant to kill off a bacterium called Clostridium difficile to re-poplate your intestines. Obviously if you don't know the person you must see a doctor.

Firstly how on earth did that come into contact with your mouth?? I suggest you seek medical help - as there are millions of dangerous bacteria in poop....
Maybe get a blood test done as well....
Go to the doctor feces anywhere is your body that is not in your intestine is toxic call your doctor and find out what you can do.
