Cold/hot....running a fever

Had to go to the emergency room last night after freezing around 4pm (then covering up w/ blankets) and then pulling a 102 temperature around 8pm. Turns out I have a urinary trac infection. So they gave me an antibiotic and scripts for two more antibiotics to start today. Well this morning around 3am, I was freezing again and woke up at 5:30 with a temperature of 103. More Tylenol and Motrin and it broke the fever which is down to 100.5. Just waiting on feedback from my Surgeon on what my next steps should be. Hope this isn't a setback. Another update soon.
