I received my pain Pump over 2 months ago. I have chronic pain from the Cervical Cancer. The pain was in my lower back and down my left leg. I would strongly recommend this device to manage your pain. I am in treatment but I pray I can reduce enough of the pain until my treatment ends. This device is to be replaced every 7 years. I would to touch base with another patient who is going through what I am going through. I think its important to learn as much as possible in order to maintain a good Quality of Living with these devices.
