Have to "flex" my muscles to feel "right," anyone else?

This is probably more of a physical compulsion, but I have to flex/stretch/massage my muscles when it doesn't feel right. It's tough trying to explain it haha. Multiple times an hour (sometimes more), I need to equally flex/stretch/massage my muscles on either side until it feels even and "right," it's usually just one spot at once (calves, wrists, neck, shoulders, triceps, biceps, etc. etc.). Does anyone else do this? I'm not really looking for advice, more curious if others experience this or if anyone knows if it's called something.
