Constant flatulence and stomach pain...

About a week ago i got food poisoning where a threw everything up and had bad diarrhea. I was fatigued and stayed in for a whole day taking pepto bismol. I was also on my monthly menstrual period so i thought that the bloating and flatulence would go away with the food poisoning, but it didn't. To this day I am still having continuous bloating and really bad smelling flatulence. My stool is still a little loose but not super watery. I have been drinking lots of water and eating healthy to try to get rid of this but nothing seems to work. My stomach is always upset and I don't know what to do. I am 21 years old. Any help or insight is greatly appreciated.
