I recently had 2 hernia repair surgeries. a few days after the surgery i begun peeing every 2 hours or so. what could this problem be?

Here are some ...: Make sure to be checked out ASAP if you have become unable to empty bladder as possibly precipitated by pain, medication, anesthesia, etc. in such clinical setting in the elderly & to confirm if you have UTI. So, collect & bring the onset, degree, duration, and progress of the voiding symptoms over time to Doc for analysis, physicals, UA, residual urine, etc. so to deduce possible Dx for Rx.
