I had pain almost all week in my upper butt area on the left side. I figured I was having muscle spasms from waking up in the morning with a charley-horse and getting out of bed too fast. It was worse when sitting, especially when driving.
Today, I still have some pain there; but I seem to have more pain in the groin area now.
Also, at about 1am Saturday morning, I had a burning sensation when urinating and also felt like I needed to go all the time (pressure). Yet when I tried to go, only a little came out with burning.
