Lifting luggage into and out of the overhead compartment in an airplane several days ago is the only trigger I can think of that caused excruciating latent pain to my right shoulder. Latent because nothing seemed amiss until two days later. It is now a week later and it seems to be getting worse. Doctor prescribed Motrin on 8 hour schedule and Tylenol as needed in between, with ice often. Been unable to stay asleep for longer than 4-5 hours per night. Hoping that imaging will guide next steps.
