You can. Do not stop training but rather just do not exercises which cause the pain.
Some things you probably won't be able to do are military press, behind the neck press, upright rows, and maybe incline press. Probably can still train back, thighs, calves, biceps (if you use good form), triceps, traps (shrugs, deadlifts), forearms, abs, hamstrings, and lol neck.
Take glucosamine for about a month like it is going out of style. This will help the injury heal. When you start back on the risky exercises (and you'll have to if you want shoulders) go light for a few weeks and use exceptional form.
By the way, how the hell did you do this?
