Darren, I can't believe what I am reading. Peripheral-neuropathy can now be reversed by practice of Neuroplasticity. A comprehensiive test by a good neurologist , will definately diagnose your condition . Don't go back to your old neurologist, research and meet with a top neurologist. Luckily you live in America. I would head straight to the Mayo hospital team. If it is established that you really do have peripheral-neuropathy, you have two choices to consider. Do nothing and suffer in silence, or overcome it totally by practicing Neuroplasticity. Like most tough times, the decision is yours.There are 2 books you should read. Details of both are in my previous posts. Recovery will require discipline and mental perseverance, but, you are still a young man, with the world at your. Just go for it

@darrenm I concur with @user_che214927 Barry's opinion to seek a different neurologist. I think doctors are not all the same and it's good to get a fresh opinion. I also don't understand your doctor's reasoning for going back on Lyrica for a month since you already saw no benefit from it before. What was his reasoning? Finally, I would really suggest you look into any new ways of determining that you truly have sfpn because of the unusual way your pain manifests. There is the skin punch biopsy option. Here is an interesting article about that:

At the risk of getting a little too arcane, there is also something that @rwinney has mentioned called confocal microscopy which supposedly can tell you whether you have sfpn. The equipment is not common, mostly at research centers and universities. I mention it just for the sake of completeness. Okay, that's it for my thoughts of the day Darren. I mainly wanted to add my second to Barry's suggestion about thinking about trying a new neurology doctor.

Good luck my friend. Hank

Darren, Best of luck to you. Neuropathy often happens after surgery as the body goes into fight mode, and you may have had an auto immune response to surgery, or some kind of nerve damage from it. Regardless, keep finding answers if you can. Lori Renee
