Do you know exactly what happened? What the injury specifically was?
At 50 years old, I trust you're smart enough to know that if a shoulder injury (or really any injury) becomes chronic now, it can thoroughly fuck up your entire training life from here on out. Healing, and healing [i]100%[/i] has got to be the priority. Whether it means physical therapy/rehab, surgery, whatever.
Especially since you don't have any concrete goals right now anyway, I suggest stealing a goal directly from Wendler when he had surgery to repair his rotator cuff and labrum:
"The simple goal was to be able to press overhead and bench press pain-free. But really, that wasn't going to cut it for me. You need to have actual performance goals, or at least I do, to make it worthwhile.
My big goal was to be able to overhead press 135 pounds correctly after 6 months. I've known many people who've done this 6 weeks after the surgery but I wanted to be patient."
The Mighty Stu also recently had his second labrum surgery (making it one for each shoulder) and also did his therapy diligently instead of just rotating quad day, ham day, quad day, ham day, calf day. Eric Cressey has written a ton about shoulder health, mostly from his perspective working with athletes (baseball players in particular).
Not the advice you wanted to hear, but IMO, it's the better path.
