Thank you for all the info.

Going back to the clinician (sports ortho doc) before going to PT would mean canceling the PT appointment (no big deal), scheduling a new appt. with the doctor and waiting a couple of weeks, then asking him for further evaluation to inspect these issues before going further. I'm afraid he'll think I'm overly analytical and not trusting his initial judgement, or wonder where I became so informed to ask for this.

Is that common and reasonable? I completely understand your advice, and want to get the best possible rehabilitative and preventative treatment now, rather than having to return time and time again over the years.

This doctor is reputable in his field, and has a special interest in RC repair, so it seems he'd have covered everything..... but, perhaps not. He did ROM and other tests that my initial ortho doc did not.
