### Patient: Doctor, I have been having sharp abdominal and back pain for a few days. I have also been experiencing vomiting and pain on one side of my body. What do you think could be the problem?
### Doctor: Based on your symptoms, it seems like you might be suffering from pyelonephritis, which is a bacterial infection of the kidneys and the urinary tract. We will need to run some tests to confirm the diagnosis, but it is important that we start treatment immediately to prevent any further complications.
