 [ Symptoms ] i am concerned about this open sore on my face [ Disease ] i think you have hit the nail on the head usually when someone describes pain or sensation as electrical  we think it is 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 is possible you are 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 is 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
