PAIN MANAGEMENT DEVICE
FIELD OF INVENTION The present invention relates to a pain management device for providing electrical stimulation topically to an anatomical state that is covered by bandage to control and manage pain.

Pain management (also known as pain medicine) is a branch of medicine that employs an interdisciplinary approach for easing the suffering and improving pain. The use of TENS (transcutaneous electrical neuro-stimulation) have been traditionally prescribed in the medical industry for chronic pain. TENS devices are usually large and require lead wires running to each electrode, making them difficult for use at home, at work or at play.
Previous attempts were made to improve pain management devices.
