Humerus/shoulder impact injury

Hello, I suffered a humerus fracture with an impacted head a month ago - from a trip while running. I am looking for anyone who has dealt with a similar injury and got range of motion back or dealt with less than great range of motion in the shoulder. The orthopedist said there is a real risk I will not be able to extend my arm. Apparently surgery likely will not help. He said I would "be able to do my hair" but I could not care less about that! I just want to swim and not the dog paddle. I have looked at lots of the shoulder posts. Today I can touch my nose. Seeking success stories or stroke adjustments. Yes, I am getting another ortho opinion. Thank you!
