The sensation of pins and needles in the fingertips needs to be analyzed in the context of the patient’s medical history and the causes of the onset. For example, if the sensation occurs after the patient has been in one position for a long time, it should be considered that the nerve root has been compressed. The most common clinical cases are neurogenic cervical spondylosis, damage to the median nerve and ulnar nerve, which may also cause the sensation of pins and needles in the fingertips. If the patient has diabetes, it should be considered to be caused by diabetic peripheral neuropathy, because of poor blood sugar control, microcirculatory disorders, and demyelination-like changes in the nerves, which will manifest as numbness and tingling at the ends of the limbs. This kind of problem can be improved by taking oral nerve-nourishing drugs to improve the symptoms, or doing electromyography to clarify.
