I broke my left collar bone playing football 4 years ago back. It wasn't nasty, just a clean snap in half, and I never got a surgery. It healed in a way that one half is on top of the other half, so it has a bump that sticks out. When I try to front squat anything past 135, the bar pushes against the bump and the pain is excruciating. What are some remedies for this? I want to front squat to grow some damn quads to help with my back squat.
