Wow, it really sounds like you did a number on your body!
Congrats on making money through dancing, and I’m happy to hear that you’re excited about it! Sounds like you had a lot of fun, too.
The balance, I think, is going to have to be in not killing yourself like this every time you go on stage 😉 Transitioning from playtime dancing, into work dancing, just like any other sport can really do a number on your body.
I would highly recommend making SURE you stretch (not flexibility training!) for your days off. Maybe some light yoga (like, REALLY LIGHT yoga) in order to make sure your muscles aren’t cramping up, and you’re getting the blood moving.
I’ve heard that foam rolling can help with the delayed onset muscle soreness (also known as DOMS, in case you want to look it up), but make sure to take it easy there, too.
I find that a good bath helps, as well as a shower in which you switch from hot to very cool (not to the point that you’re either burning or shivering, but making sure the temperature difference is clear to your body). If you let yourself get used to the temperature before switching, it can be quite effective.
Massages for relaxation can also be super amazing, if you can afford them.
Sleep, eat lots, and drink lots of water!
For your feet… well, that’s going to take time to heal. I don’t have any special healing magic for that 😉
You can always look up other methods, too. These are common ways, and I’ve found them to be quite effective. You might find some others 😉
Good luck!
