Hello Laury Klasky,
Definitely listen to your body and your doctor’s advice. Please do not push yourself to jeopardize the healing process, it is not worth it.
You are using more than you may realize right now: the body’s immunity is lowered while healing after surgery, among other considerations.
If you must teach, please try to do it without activity.
Karin Singleton could not say it better, having been through this herself.
The better you care for yourself, the faster you will heal…permanently.
Good luck for a speedy recovery.
Please take care of yourself that you may care for others.
