Patients playing cell phone hand trembling should be treated for the cause: 1. If the patient’s hand trembling is caused by playing cell phone for a long time, in this case the patient should immediately stop playing cell phone and massage the muscles of the patient’s hand and elbow to improve the patient’s symptoms. 2. If the hand trembling is caused by idiopathic tremor disease, the patient’s hand will also tremble when playing cell phone, in this case the patient can be given oral propranolol to reduce the symptoms. 3. If the patient’s cervical spine curvature is inverted or there is a herniated cervical disc that compresses the dural sac because of frequent head bowing and a posture for too long, it will also cause the patient to experience hand tremors. Patients in this situation should consult an orthopedic surgeon for massage, traction, massage, acupuncture and other treatments to improve the patient’s symptoms.
