Two days ago I fell off the treadmill and hit the bionic knee against the wall. It has been quite sore but not swollen. Dumb as I am I kept working out (less cardio than usual but still 2 sessions of 20 min a day) and I also did legs (high reps, low weight). Thing is that the knee is really sore (inside compartment and patella). Just wondering what I should do next.
