As a very outside possibility, I had the following happen to me once. I had a friend’s family come visit us for a week, but I was getting over a cold and didn’t want to have cold symptoms around them, so for that week I was taking, guaifenesin (expectorant), dextromethorphan (cough suppressant), and Sudafed/pseudoephedrine (decongestant).
For that whole week I had to pee constantly and I was wondering why it took me 3 whole minutes to pee, and when I was done I still felt like I had to pee. And this repeated itself every 45 minutes. I didn’t have time to think about it much while it was happening, but later I realized that my prostate must have swelled up due to the combo of those cold meds (which are pretty common cold meds). That was a nightmare and I’ve stayed away from those ever since.
