The symptoms seem to indicate that the scrotum has been decoupled. This requires that you perform a routine X-ray or MRI scan procedure. When diagnosed, you can discuss treatment options, such as physical therapy, splints, or, if necessary, a joint test. You also need treatment for this if you have a non-fracted fracture or defibrillion.
Doctor, there's so much pain in your knee that you can't get it right.
