Hello, I Have Recently Been Diagnosed With Exciting E Coli

Hello, I have recently been diagnosed with exciting e coli with the Shigella Toxin. I though I had food poisoning a few months prior I lost 10 pounds (from 105 down to 91 lbs, fever, throwing up and diarrhea) then I have been experiencing lower left stomach cramping and discomfort for the past few months as well . So I had a stool sample done and we found what it was. In the past week I have become extremely lethargic, sleeping for about 12 hours and still be exhausted throughout the day. I also do not sweat very much, and what started out as night sweating one night every two weeks, has turned into me waking up with my sheets soaked for the past three or four nights. I called my doctor and will go in for a check up on Monday if its not better, however wondering if any doctors out there have experienced this with patients previously. Thank you for advice.
