Been sick two weeks..regular doc thinks it's a virus or c diff.feeling worse now102.2 fever and belly pains gotten worse.can i go to urgent care?

You should,,: You should get to an er or some other urgent care center like a hospital and get worked up. According to your history you've had surgery and if it was recent you could have an infection like c diff. Complicating it or you might've ingested some food that might have been suspect. Either way it's important to find out what it is and get treated soon. Best of luck.
