Sleepiness in the arms is mainly due to the following reasons: First, patients who have been engaged in heavy physical labor for a long time in their daily lives or who have been lifting heavy objects for a long time or who have been working at a desk for a long time will cause local muscle damage and induce symptoms such as drowsiness and even soreness. Secondly, it may also be due to cervical spondylosis or frozen shoulder, which may cause drowsiness in the arms of patients. Third, it may also be caused by peripheral neuritis or local nerve entrapment, which may lead to drowsiness. For example, brachial plexus nerve entrapment syndrome may cause discomfort. Patients with arm drowsiness are advised to apply local heat and massage or local acupuncture to relieve the condition. If the patient still cannot be relieved, it is recommended that the patient go to the hospital in a timely manner.
