I recently slipped and slammed my leg against my desk. In doing so, it hurt extremely bad. It's not broken, but across my entire outer thigh, it feels brusied. It hurts to walk or move or even touch it. There is no markings though, as if it would be bruised, though it feels like it is. It there something I can do for the pain? Is there a bruise under the skin maybe? The muscle bruised?
