I Was Recently In The Hospital For An A FIB

I was recently in the hospital for an A FIB and my cardiologist asked if it burned or stung while urinating. At the time, no, but a few days later, yes it does. I didn't ask why she asked as I was ready to get the heck out the hospital. It's been two weeks since I was admitted and released. I was there from Wed evening to early Friday morning. I am experiencing a burning sensation when urinating now and stream interruption. Why would she ask if it burned, and should I make an appt asap? Thank you
