It had to be traced back to 2014 when I had a urinary tract infection and was given Bactrim. It lasted more than 1 year and then the trouble began. I developed a bad pain in the right side of stomach, loose motions. It even hurt to walk or drive a car. I couldn’t eat as well. I went to see the doctor for many times, but no disease was diagnosed. In 2017, after several visits to a new young general physician, she wrote told me it was C. Difficile. Well, it was totally a mixed blessing.
