Xrays won’t hurt. But a torn rotator cuff is diagnosed with an MRI. The problem is that upwards of 20% of people over forty have torn rotator cuffs and are asymptomatic. Good luck.
She’s eliminating a broken bone or dislocated something from possibility. Thinks I should wait a few weeks in a sling with anti-inflammatories if there’s nothing bone-related to see how healing goes to decide if an MRI is necessary. (Hoping no surgery.) Though, I suppose it would make sense to get it all done at once. Also, she seems to think it may be a terrible sprain as opposed to a torn rotator cuff.
