Vibrations, yes. My calf muscles felt like lead bricks. Teeth, I can not attest to. Each person and their symptoms may vary.

albeit, your symptoms could be something else, they don’t sound like typical SFN although there are many and can vary from person to person. If you type in your symptoms using your search engine you’ll find many possible health issues that can cause them. Hope this helps. Helen

For what it's worth, aside from burning feet, pins/needles, and occasional zaps - the intermittent sensations I've experienced that my neurologist confirmed are due to SFN include:

* Sense that the skin on the ball of my feet had thickened (calluses) - although when I felt the area with my hand it clearly has not.
* A feeling in my calves as if the muscles were popping like popcorn. Not painful - just super irritating.

I'm still waiting for the Gabapentin to let me know whether the aching/stiffness in my feet and ankles is related to SFN or if it's something else. I can say that a little more than one week in, and just 2 days on 200 mg (taking it at night only) the aching and stiffness does seem to be reduced - but I will take a wait and see approach to see if it's the Gabapentin or short term coincidence.
