Blister: pad with gel squares (second skin) during the day when you have to move around. At night, elevate your foot in open air, no blanket on it. Do not let anything touch it if it's popped!

Crick in the neck: apply heat (ex: towel drenched in hot water) and lidocaine twice a day, massage nightly, sleep on back with flat pillow.

Sprained toe: ice & arnicare cream every 6 hrs, elevate every night, try to wear open-toed shoes. When dancing, bind to adjacent toe (like a splint) with toe tape. Do not add extra padding, it increases pressure on the toe!

Ankle sprain: wear compression sock to minimize swelling, apply ice, and elevate at night.

I am not a medical expert! These are just remedies that worked for me.
