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. |
Mrs D, in a few sentences you have logically answered the question that I have puzzled over for years!
Thank you!
My small-fiber neuropathy is typically in my palms, and I will unfortunately feel tingling and sometimes burning as one of my first sensations in the morning as I awake.
However, within a few seconds of my getting out of bed the pain seems to literally fade away. I will also notice the pain during the day when I try to take a nap, so again this makes perfect sense!
You are such a wonderful resource!
