<human>: My knee started popping everytime I move about a week ago. It pops when I stand up, walk up stairs, or ride a bicycle. I had twin boys in November so I recently started running to tone up but had to stop due to my knees hurting. I am just wondering if this is normal or may be some sort of problem.
