Has anyone tried a device called HF 10 ? It’s a device which stimulates your spinal cord to help relieve back and leg pain. After a trial period of about a week, if the patient is achieving good results the device is implanted in the person. My pain management doctor has recommended it to me for arm and hand nerve pain. I would like to hear from anyone who has used this device and especially from anyone who has used it for arm and hand pain. Thank you.
