Hey, we just repeat what the books we studied read to us. Hahaha!
Even after surgery, you might be able to still ride. The doctor is just covering his ass by telling you to quit. That way if you do have an accident, he can say "Hey, I told him not to anymore". It seriously is a liability issue.
My roomate had a pretty bad motorcycle accident about 1 1/2 years ago. He's back on and feeling like a million bucks after 5 screws in his shoulder from a 180 degree slap tear. So, don't always suspect that surgery is a bad thing. I mean yeah he has aches and pains still, but it doesn't keep him from riding!
Good luck man! Let me know if he tells you something that don't sound right! :thumbsup:
