The coldness of the back of the right hand and wrist may be caused by the lack of warmth, or it may be caused by cervical spondylosis, peripheral neuropathy, thromboembolic vasculitis, or arteriosclerosis of the upper extremities.
1. Lack of warmth: the hands are kept in a cold environment for a long time, and the lack of warmth causes physiological coldness of the back of the right hand and wrist.
2. Cervical spondylosis: Hyperplasia, degeneration, deformity of cervical spine joints, herniated intervertebral discs and other changes lead to cervical nerve root compression and stimulation, resulting in abnormal sensory and motor functions of the distal radial nerve, median nerve, etc., and thus the back of the right hand and wrist are cold.
3. Peripheral neuropathy: diabetic peripheral neuropathy, Guillain-Barré syndrome and other diseases involving the right upper limb nerves, resulting in abnormal function, resulting in the back of the hand and wrist of the right hand cold, local numbness and other symptoms.
4. Thromboembolic vasculitis: chronic inflammatory lesions of the arteries and veins of the right upper limb lead to poor local blood flow and lack of blood supply, resulting in coldness of the back of the right hand and wrist.
5. Arteriosclerosis of the upper limbs: atherosclerotic lesions caused by high blood lipid levels, resulting in localized narrowing of the arteries of the right upper limb, lack of blood supply to the back of the right hand and other parts of the right hand, and coldness of the back of the right hand and wrist.
These are only some of the common causes. The coldness of the back of the right hand and wrist may be related to a variety of factors, if the symptoms persist, you should consult a doctor in a timely manner, after a clear diagnosis and standardized treatment in accordance with the doctor’s instructions.
