Hello. I have not personally tried it. My best friend did and woke up from the anesthesia screaming, she felt like she was being electrocuted. The Doctor had forgotten it to turn the device off/down before installing under skin. She yells it from the roof tops DO NO TAKE THE RISK>she still suffers every day. When we are in chronic pain we will try anything, but we must learn from others. SO Sorry. I know in this 22 century and we still can not get pain relief.
