Is it beneficial to pinch the tendons on the shoulders?

Generally speaking, kneading the muscles on the shoulders can be beneficial. The specific analysis is as follows:

The muscles around the shoulders often become tense and painful due to prolonged sitting, work-related stress, or overuse. Kneading the shoulder muscles can stimulate the muscles, help reduce tension, and alleviate pain. At the same time, this kind of massage improves blood circulation in the area, helping deliver more oxygen and nutrients while aiding in the removal of waste products and metabolic byproducts, thus promoting muscle recovery and repair. Additionally, kneading the shoulder muscles can help relax and stretch them, improving muscle flexibility and range of motion. Therefore, kneading the shoulders is beneficial.

It should be noted, however, that although kneading the shoulders has benefits, it should be done in moderation. Excessive or overly forceful massage may lead to discomfort and should be avoided.
