I'm having really bad discomfort I need a release asap?

It started about two hours ago I keep feeling like I need to pee immediately but when I go its a trickle its like a discomfort feeling with a little pain if I push the pain releases I've read it can be symptoms of a water infection but its come on sudden and I've had water infections before but never like this, is there anything I can do to ease the pain untill I see a gp on Monday
