I might get hurt, patting myself on the back so hard. ;)
A regular client of mine who'd been having problems with his right shoulder since before he started coming to me FINALLY got an MRI. His doctor, who had insisted that it was bursitis, was surprised to find a fairly severe rotator cuff tear and scheduled my client for surgery.
I, on the other hand, wasn't surprised at all. I had told the client at his first visit that it sounded like a rotator cuff injury to me, and that he needed some better diagnostics done.
Of course, diagnosing and/or treating any kind of illness or injury is outside of my scope of practice.
But I knows what I knows.
