The body muscles often jumping, may be related to the following causes: 1, may be due to over fatigue, such as patients after doing strenuous activities over fatigue, may produce involuntary muscle twitching of the limbs. 2, may be due to excessive excitement caused by, such as patients in high tension or sleep process, nightmares, often manifested as the peripheral muscles appear involuntary jumping, sometimes accompanied by involuntary activity. 3. There may be central neurological lesions, for example, when there is a lesion in the cerebellum, there may be muscle twitching, and there may be ataxia, such as unstable walking or hand tremors when holding things. Patients with this condition need to rest thoroughly, and may also undergo physical therapy such as acupuncture or tui-na. Most of this condition will resolve on its own, but if it persists, you need to go to an orthopedic clinic.
