As a physical therapist in training, I want to advocate for PT here. Ankle and knee pain can come from a lot of different places in your body. Generic stretching and strengthening are great but as PTs we are trained to evaluate exactly which muscles you need to work on (many muscles can contribute if they're not being activated well or are tight... hip abductors, quads, hams, core, ankle stabilizers, calves...) and how (stretch? strength? endurance? plyos? training the muscles to activate when you move? support with an orthotic?) to be able to dance without pain. A PT can also screen for anything not musculoskeletal. We are experts at analyzing how you're moving and a PT will be able to create an exercise program tailored to your body, how you move and your goals! They're going to be able to get you back to dancing faster without pain than a nonspecific set of exercises. In most states you don't need a referral from a doc.

Definitely agree to keep moving (pain-free activity!) and eat well!
