Did your doctor give you an idea... they usually do or atleast the one's that patched me back togther anyway.
It all depends on the break, where it is, how good your body heals, and a lot of things. Best I can tell you to do is follow your doctors directions and then get out there. I got to hunt 6 times last year 5 of which was only half day hunts and that is the most I have hunted in the last 8 years so... it wont kill you to miss the beginning of bow season. Just heal up and get back out there.
