yes. you can bowhunt with a bad back. even if its your upper back thats the problem area. i have had a messed up rotator cup and all the muscles from my left arm up to my neck and halfway down the left side of my back severly pulled. i live everyday with some pain. yet i still bowhunt. like posted above, just go to a pro shop and ask to try a few bows. i also keep my peak weight under about 55 lbs. and cant shoot more than 15 rounds of 3 arrows. get out there and do it
