Ok this is just an experiment but you should try it. My grandpa did it to me(hes not Asian)but he saw something about this on the internet and I didnt really have any injuries but its worth a try. You find your center and just kinda push the air around the wound. Your suppose to inhale through the nose and exhale through the mouth. I wont put much faith in this but its worth a try see if it makes any differences. Experiment with it. Your mom sounds like an open minded person so if she will try that maybe it will work. She is in my prayers man I know what its like to have someone you love in constant pain. Be strong.
