Does anyone have less pain while walking?
 

It seems most people have more pain when walking. I find it worse when I am sitting down.

Yes, that can be the case. I have SFN symptoms from tip to tail. Lack of movement can be painful, so I tend to make sure I move around at certain intervals. However, I also have to be careful not to excessively overstimulate my sensory nerves with too much movement as well. It's a delicate balance.

Miving makes the pain less. Sitting or lying down is much worse

I explained this on another thread here.

There are 4 types of sensory nerves in the periphery.... The positional fibers... alpha type, are the most myelinated and fastest in sending signals back to the brain.

The others decrease in myelin, and thus the speed goes down.

There is a priority in sensation, with the nerves and brain interpretation. Since it is critical for the brain to know where the feet are, and other movements, those alpha fibers have priority. So when you are moving round, you don't "feel" the others the same way you do when you are still.

This goes for other types of pain too.... and dentists often use distraction to minimize perception of the needles used with Novacaine numbing. With children, distraction is often used when they get needles too for tests, etc.

Within the temperature sensory nerves, there is a priority for cold over heat. This is why topicals, like Biofreeze turn off burning pain in the feet and hands. Menthol stimulates cold receptors, which override the heat ones.

The movement is not "treating" the cause of the PN though, only temporarily blocking the messages.

Tuna it me too that's when I found out I have a herniated disk in my back
