Can A Fracture Cause Numbness And A Bruise On The Leg?

Good evening. I am a 49 year old female. i was in a horrific car accident at age 15 in which one of the injuries was a compound fracture in my right tibia and fibula. I also later found out a couple of years later that I alos had a fracture under my right knee cap. The ortho doctor set the bones (no pins, plates or screws). I spent almost two years in a cast. My right leg is about 1/4 inch shorter than the left leg. I was at the gym three weeks ago and used their shaker machine . I basically stood on this crazy vibrating base for ten minutes. I knew that something was wrong almost immediately after I exited the machine. Since then, I have had horrible bruising in the area that had been broken. I also have numbness in the area as well as in my ankle, foot and toes. My leg and foot have a yellowish blue tint and feel as if I am walking differently on my right foot. Could I have broken my leg? What should it do?
