The main reason for the performance of acidity and weakness of both arms is that the patient’s upper limbs have too much weight-bearing activities, resulting in the accumulation of lactic acid in the muscles of both upper arms, which will produce local muscle acidity, weakness, pain and swelling. In addition, the patient has bilateral upper limb neurological lesions, can also lead to this phenomenon, for example, the patient suffers from neurogenic cervical spondylosis, due to the nerve roots of the neck, the stimulation and compression, will affect the arms have muscle weakness, numbness, weakness, or the emergence of pathological reflexes. A clear diagnosis can be made by electromyography or by taking MRI films of the neck. Prolonged exposure of the patient’s arms to cold affects the operation of qi and blood in the arms, resulting in stagnation of qi and blood stasis, which also leads to a gradual decrease in the absorption of nutrients by the muscles and the clinical symptoms of muscle weakness.
