He asked me the popping and clicking question, i wouldnt call it a click but there was a scrunching noise when i moved it.
I went at the end of the day (i continued snowboarding after fall) but went at around 5 oclock to the doctor.
He couldnt of asked about sleeping on it.
He did the external/ internal rotation strength test. Arm raising to front and above head. Pain was only felt raising arms above head.
Your right that the science is not yet definitive, and their are still some things that doctors just dont know what to do about.
I know a bodybuilder (IM a dedicated lifter), whose right shoulder gives out just outta the blue, Its not a joint but a nerve problem. Literally his brain just stops sending messages to his shoulder, and the doctors dont have any solution.
