i think you've hit the nail on the head. usually when someone describes pain or sensation as "electrical " we think it's nerve-related. the same is true for pain described as stinging shocking or burning. if the sensation occurs all the way from the shoulder to the fingertips then it's possible you're experiencing a spinal nerve compression at the neck. if the sensation is more from the elbow on down or something then you may be experiencing irritation or compression of a nerve where it goes through a joint like the elbow. you can find out for sure what's going on by making an appointment with your primary care provider. he or she can evaluate the situation and send you for tests or refer you to a specialist. hope this helps!
