Muscle tension is often characterized by the following: 1. There is a marked increase in muscle tone. If the patient continues to have muscle tension, it will lead to a very high tension on the surface of the muscle, that is, when it is touched, it can be felt to be very hard. In addition to this, the continuous contraction of the muscles results in very high tension in the patient’s joints. For example, when the patient’s joints are passively moved, it will feel very stiff.2, may cause continuous muscle tremor, in the continuous muscle tension, there will be fatigue here, which will cause muscle tremor over time.3, may be accompanied by obvious pain, in the muscle tension, may be due to muscle spasm or muscle fatigue, which will lead to the muscles have a 4. There may be a particularly pronounced spasm of the localized muscle, which in turn causes a nodule. For example, in the presence of persistent muscle tension, there may be very obvious spasmodic muscle blocks or muscle strips at the muscle belly.
