Quick update: I felt OK the first few days after my biopsy, but then something didn't seem quite right. I was having a hard time taking a deep breath and overall just felt a little bit "off."
On May 28 I went back to UM and was diagnosed with:
My doctors ran several tests, debated a CT scan, and opted to take the "wait and see" approach. They had me come back on May 30 to repeat the tests. And they called me on May 31 so that I could describe how I'm feeling.
My fever is gone, but the flank discomfort remains.
I'm hopeful I'm on my way to feeling better.
