See doctor's answer to my question under PAD (peripheral arterial disease)
Hi, hand tingling could be due to neuropathy associated with cervical spondylosis, carpal tunnel syndrome, vascular insufficiency, calcium and vitamin B deficiency, thyroid disorder etc.
Please elaborate the symptoms, which portion of hand is affected. How old are you and do you have diabetes?
It could be carpal tunnel. Is the tingling in certain fingers? Does the tingling or pain go anywhere but in the hand?
