I did something similar to my back a few years ago. I was pulling an arrow out of my 3d, and after that, couldn't shoot for weeks other than a 20lb recurve. it did heal though. I'd get checked out, and be careful, take care of it. even it you could draw it but it isn't comfortable for opening day, I'd let it go. better to rehab now and be able to hunt later, and not hunt now, but not later.
