Last week during a test, I had to hold in my urine for about 2 hours. Ever since then, whenever I need to urinate, I cannot hold it in for more than 30 seconds to a minute. This is really frustrating because that means that I have been needing to rush to the bathroom so that I won't urinate myself. This is really unusual for me, since before holding in my urine for that long during the test, I used to be able to hold it in for about 30 minutes, easily. What could be the problem?
