I agree with the others. (Probably not that big a deal to not get the skin punch. It seem like only a limited number of people do get it.)

The symptoms you described do sort of fit the type of odd symptoms that SFN causes. Mine started almost 5 years ago with a sudden onset of muscle tightness, then twitching and cramping. After many Dr. visits and tests still no diagnosis, but almost certainly SFN. Things got better but still some foot pain. I take some Gabapentin to control it. I'm still working in a job that keeps me on my feet a lot.

It seems no two people with SFN experience exactly the same symptoms. And no way to predict if it will get better, stay the same, or get worse. (The people who frequent the forum here tend to be ones with ongoing and progressive issues, but I think that's because the ones who get better don't see the need to continue coming here.) I like to come back at least once in a while to check in and let people know it's not necessarily doom and gloom
