My teacher was very well known for his herbal and tui na techniques. One that I have come to rely on is the torn or pulled muscle powder. It will take tha burn out of torn muscles and promote the healing that is needed. I don’t know how long your muscle has been torn or stretched. I couldn’t get onto the form for over a week. If, you would like to try the powder I will give it to you to try. You can just pay the shipping which shouldn’t be very much.
