Went to a TCM to do tuina, he said my backside is curved outward and he tried straightening it and the pressure from the bones at neck area is obstructing the Qi from going up to the brain. Lots of twisting and contortioning act. I feel sore on my back but good kind of sore. We went as a group. The sensei treated my friends mom from a major problem and she used her connection to secure booking for our treatment. He is good.
