Then come the other fibers. These are slower ...so when your feet are still they start to send their messages.
Here is a link explaining the 4 types:

At one time I found some other explanations about efferent fibers. The cold sensing ones mask the heat ones, and that is why many remedies have menthol/camphor in them, to stimulate these to block the burning sensations. Biofreeze is one of those topical things that work well, for excessive burning. |
This is so useful and interesting to learn more about thank-you again Mrs D. It makes complete sense that the SFN is so painful at night now you've explained.
But my legs and feet, hands and arms and sometimes my neck, shoulders and back all constantly feel as if they have camphor/ menthol rubbed on them anyway during the day so I don't think I'd want to treat this with the real thing? Or maybe this would help with the nighttime pain - which is more like neuralgia on my feet, the inside of my ankles, shins and knees all the time. I would far rather use a topical med although my skin is very sensitive.
