me and some co-workers bought some boxing gloves and fought the 2 days ago. immediately after the fight i had a dull pain in my left shoulder depending on how i moved or raised my arm.
ive slept and ate like crazy but my arm still has a slightly dull ache.
should i avoid any shoulder/ chest movements or would it still be okay to work out?
also ive heard about rotator cuff injury prevention exercises should i try those?[/quote]
Avoid any and all movements that cause you pain or discomfort, preferable any movement with that specific joint.
Working out in general is ok, but since the shoulder is involved in almost any exercise in some way or another (even if its only stabilizing), you should maybe do some leg/core work (on machines if you have access)
If the pain isn’t completely gone after ~3-4 days, go see a specialist.
One should always do some rotator cuff work, there are a dozen articles on that topic on this site alone.
