Healthcare and Medicine! A display of a human spine, spinal cord or vertebrae, with a TENS (transcutaneous electrical nerve stimulation) unit attached for pain mediation. The small metal unit would be inserted under the skin, and the wires (or leads) attached to the spinal nerve causing the pain. Pain treatment comes in many forms, and this one is an advanced treatment, alleviating the need for medications to be taken by a patient. If connected properly, good results should be expected.
