Closure: Thank you for letting me examine you today Mrs. Jones. I understand that you’re worried about what may be happening. Based on the history and physical exam there are a few possibilities. You may have some of these issues due to an acute situation where your spinal cord is compressed and we need to do some imagine to rule that out quickly. Also, it is possible that this could be due to an infection and we are doing to run some blood tests and get a urine sample to investigate that . Does that sound alright to you?


Labs:

-Lumbar MRI
-U/A with culture
- Electrolytes (fluid status)/CBC (wbc)
-Pelvic exam (Qtip test)
-Blood Culture
