Absolutely, some things we actually need surgery for. But most of the time it's not necessary and really the only solution is to fix poor movement patterns and to strengthen the body. A lot of back pain comes down to strength and flexibility issues.

For my shoulder the main thing that worked was getting into the habit of doing pull-ups and stretching out my pec minor. Anytime I neglect pull-ups for a while the discomfort will creep back in. I probably should also buy a split keyboard.
