I have had a kidney infection for over 3 weeks now, and it is getting worse and worse. I am now on my third round of antibiotics and nothing has helped me. I cannot keep ANY food or drinks down, severely sweating (but NOT hot), chills, dizzy, weak, no appetite, shaking, loosing weight FAST (21 pounds in 2 weeks), body aches, pain in the upper stomach, pelvic/bladder area, and back, and VERY nauseous. Please help, and give me suggestions on what to do, and what to eat maybe. Thank you.

P.S. I was on two rounds of Cipro and now I am on Keflex if that helps.
