Totally agree. First time I've ever seen anyone say this. I'm not sure how a sports doctor or physio is going to fix a swimming injury without understanding the fundamentals of the freestyle stroke. The issue would be an ineffective stroke, which is overloading the shoulder causing tendonitis. How is a PT who isn't a swim specialist going to diagnose this? As Dr T says, they'll just say it's tendonitis, give you a cortisone shot and a bunch of useless strengthening exercises with a band. There is nothing wrong with the shoulder joint or the rotator cuff, it doesn't need to be stronger, it needs to be not overloaded! And that's done with stroke correction, something a doctor or PT (with no swim knowledge) is not going to be able to fix.
