For patients with arm drowsiness: First, it can be seen in cold, which can easily lead to spasm and edema of the muscles and fascia in the arm area, thus leading to arm drowsiness. Second, it is seen in the middle-aged and elderly people who have bone degeneration, hyperplasia and osteoporosis in the arm, which will also lead to obvious drowsiness and soreness in the arm, and painful symptoms when moving the arm. Third, in patients with neurogenic cervical spondylosis, the nerve roots entering the arm are compressed in the neck, causing a weakened nerve conduction, resulting in the loss of innervation of the muscles and fascia in the arm, thus causing symptoms of drowsiness in the arm, which can lead to pain and weakness in the arm after a serious condition.
