JLL - I was going to offer my own pain issues until I read your post. I can't imagine having to teach while going through chemo. Just to give you some inspiration though - I had a student last year diagnosed with cancer and she continued dancing. Her doctors had said she should dance if she felt up to it, but they couldn't believe that she never missed a class. She wasn't always able to complete every class but she was an active member. If you asked her she would tell you dance is what got her through it. She is now cancer free and back dancing full time! I hope things just get better and better for you.
