I am currently on vicodin, cymbalta and gabapentin. All if which help at the very least. However, I am not going to stop taking them because, if this is the only pain relief that I will get, then I would rather take that tiny, tiny, tinybit of relief, rather than nothing at all. I have done three nerve blocks, which helped for a few hours, but by the end of the night, my pain was off the chart, and back to "normal" as usual. My pm said that he did not want to give me any higher opiate because he is afraid that I may become addicted or it may be harder for me to come down because, I may want to keep going higher and higher in search for a stronger pain killer. Don't get me wrong, I know none of these meds will completely remove the pain, but I do not feel that my pm will give me anything stronger. my occupational therapist suggested that I search for an rsd specialist. However, my pm dr. Is extremely nice. I have heard of the ketamine, but I don't think I am ready for that yet.
