You're coming off an injury, If you move anything and the bike doesn't feel right, you have no idea if it is the bike or you, Keep it simple, Only change should be to raise your stem a cm or two until you feel better and stronger and it is time to push it back down (probably in two smaller steps). (I love the old quill stems for exactly that reason. Mark it with tape before you raise it.)
Trust me. I've had enough injuries and comebacks. While on the comeback I bike you know works is a huge asset. (New, you may have to tweak things for your injuries. Document what you did so you can go back exactly.)
When your back riding and strong, only then should you start changing the fit.
