This morning, I went to urinate but it turned out I really didn't need to. However, while I was in there I experienced a major burning sensation in my groin on the right hand side. This lasted only a couple of minutes and I was fine the rest of the day.

When it happened, I suddenly recalled occasions in the distant past which were similar but with much less discomfort. That was years ago, and it hadn't happened at all again until today.

Beyond this, I have no out-of-the-ordinary symptoms to speak of. Anybody know what it might have been?
