Hurt my left shoulder today

I strained to get the last rep with a dumbbell doing standing curls at the gym at my resort - last day of vacation and I felt something crunch in there - no pop, but definitely a crunch.

At my age of 46, I feel it may be time for a cortisone shot in my left shoulder. I had one last year in my right shoulder as my doctor was trying to eliminate any possible muscle issues before my spinal fusion surgery in early January. The accidental result is no pain at all in my right shoulder - I was an amateur baseball pitcher and catcher until my late 20's so I've gone through a lot of shoulder pain over the years - the right shoulder feels great!!!

For those my age that lift, how many days off would you take from this type of exercise? I think I can get away with the machines for a few weeks before I can get in to see my doctor.
