The same medicine, the same temperature, applied to different parts of the disease, the reaction should be different. The burning sensation shows that this place is severely blocked by wind, cold and wet erosion, and it is difficult for hot moxibustion cream to penetrate into it. This will happen. If you keep applying it every day, you will get better and be more relaxed. If the local feeling is very cold, it means that the cold is very heavy and is being pulled out of the body by hot moxibustion, and the body is gradually getting better. Just stick to it slowly.
