I had that for a little while. But I didn't get it checked out 8-[ It was a wierd ache that I got for a bit after urinating (not during). And it would only happen if I'd let my bladder get too full. It was almost as if I'd pushed the urine out too fast and hurt the muscle.. if you know what I mean! :-s

I thought UTI had a burning sensation, and constantly feeling like you need to go? So I didn't get mine checked out. *shrug* Nothing came of it, and it didn't happen each time. I just put it down to extra pressure on my bladder or something.

Hope it eases up for you emz. Perhaps drink a lot of water to flush things out a bit
