I partially tore something in my shoulder (I think, did not go to the doctor.) as you experienced the docs are clowns and won’t give you an MRI without an x-ray, go to a physical therapist as they might actually be able to help you.
I initially had limited range of motion (couldn’t raise it much higher than straight out.) and stayed off the bike until I could ride with no pain. Maybe a week or so. If it hurts it’s probably a bad idea.
do the physical therapy exercises.
