Oh yeah!! I have arthritis, so occasionally I need to wrap my wrists with ace bandages for pressure while teaching. I also had a dance injury when I was 21, I fell out of a jump and smacked my tail bone, m nerves shot up my back and I saw stars. I can't really bend the same, lift anyone or do sit-ups anymore. Having my daughter and being pregnant made the injury worse. So, yeah I teach with a lot of pain.
