I don't know your details but - been there done that, Class 3 separation etc - and after removing a bit of my collarbone to alleviate the grinding and scrapping (impingement) I was back mountain biking and hiking in short order. I'm 7 years out with no restrictions or inconveniences.
If you don't have a issue with impingement you'll be going again in a week or three, otherwise surgery plus four, with good PT.
You, and 50% of the other active people in this world, will have a 1" step at the shoulder to show for your efforts. And hardly any 'glory points".
Now....back to neck pain...
