Cramps and numbness in the hands are mostly caused by holding heavy objects in the hands for a long time, local muscle strain or cold for a longer period of time, which affects the local qi and blood flow and leads to spasmodic pain in the muscles of the hands, resulting in cramps and numbness, reduced sensation in the skin of the patient, and in some cases, impaired finger dexterity. Patients with cervical spine lesions, such as cervical spondylosis and nerve compression, can also lead to neurotropic disorders in the hand, which can also lead to cramps, numbness, and pathological reflexes. After the patient has cramps and numbness in the hands, he or she needs to reduce activities and rest in bed, and can often soak the hands in hot water and use orthopedic washings to fumigate them, which can gradually relieve the patient’s clinical symptoms.
