Hey Breadman--speaking from professional experience, do NOT push yourself, amigo, okay? Ligament injuries take longer to heal than you usually think. We can wait. Ease back into work and day-to-day functioning. We know that animation and drawing isn't the only thing your shoulder is used for--presumably, you also do things like, y'know, get groceries and vacuum, which also strain your shoulder. Keep yourself healthy long-term! Being cautious now is better than re-injuring yourself and further delaying work and life in a week or two! Cheers! :)
