on February 13 I became ill, nausea, vomiting and diarrhea and low grade temp. Went to my PCP, treated for gastrointestinal disease. Given meds for nausea and a shot for diarrhea. I got worse everyday and ended up in the ER, fluilds and potassium (because my blood work shoes I was deficient). the ER PA said she did I not think it was an obstruction, and said the flora in my guts had been stripped from so many antibiotics and pain meds from the knee replacement surgery that I had on Feb 1. Here it is March 5 and I’m still sick. Any ideas.
