I have a spinal cord injury and nerve damage at the C7-C8. I had C5--C7 fusion done almost 3 years ago. I have not felt my index and middle finger in 4 years, and touching the simplest things sends me through the roof. My right arm is affected through use and pain constantly. I recently (Dec 2011) had a spinal cord stimulation implant done, and this offers very little relief, plus I cannot use it during any activity due to the intensity increasing with movement. I have been on my share of pain meds, but have yet to find anything effective. After reading reviews on hydromorphone, I am going to discuss this with my doctor. Please, if you have any input, I would love to hear it!
