Cosmetic tendon paddling can loosen muscle knots, unblock the metabolism of meridians and regulate the circulation of Qi and blood in the body, but if not done properly there may be the following hazards: 1. local soft tissue contusions: when doing this kind of massage treatment, it may cause heavy stimulation to the local soft tissue, especially if the operator’s method is violent, it may cause local soft tissue contusions. In addition, if there is an acute local injury, it is more likely to aggravate the trauma and induce obvious swelling and inflammation when doing such treatment; 2, severe pain: If the local adhesions or tendon lesions are very heavy, it may induce very serious pain, which is especially obvious in people with poor pain tolerance, and patients with heart-related diseases need to pay extra attention when doing such treatment. 3. local aseptic inflammation of the tendon: common in those who operate too frequently, which may lead to aseptic inflammation around the tendon and aggravate the condition; 4. short-term soreness and weakness: common in cases where the operator’s technique is too strong, or the patient is weak.
