My cousin completed physiology degree, then went for a fancy chiropractic program in upstate NY. (he is also married to a dietician / counsellor). His specialty is rotator cuff and other sports related injuries. And yes, he was a member of the ski partrol and is avid hiker/ adventurer.
I think he would recommend getting massage therapy training. He had to take it as part of his first year of his Chiropractor training, as it intensely covers musculature, ligaments, and (I think) bone structure. Plus, you know, hands on. He will never be a licenses massage therapist, but found the training to be the most valuable out of everything he took.
Turns out there is a lot of cross over between massage therapy, physio therapy, and chiropracty, at least here, for the licensed practitioners.
You might find that a traditional, formal university program may teach you the same (intro level ) items your doctors learned, which, as you found, was not practically helpful.
So - it is a question - what do you want to learn?
