@Ialan, I got a bit confused in that the original post of April 2018 was someone concerned for their dad. Yours is a concern for your son? The pain from neuropathy can be miserable. I’ve had it. A few days ago I suggested some temperature related things to try that helped ease my neuropathy pain. Also massaging these extremities was helpful. I did not find medication to be beneficial. I’m especially concerned with pain medication such as hydrocodone as it can merely mask the symptoms and can be addictive. Who do you have among your providers to help monitor the use of this med?
