I agree it seems like the nerves in my feet start giving me trouble when I get in bed. I noticed putting my knees together makes it worse too. I have tried capsaicin lately, on top and bottom of my feet before going to bed. I used to lay on my side all the time but now I have changed to propping my head up more and laying on my back. It has calmed my feet more. Before that I used Vicks vapor rub, it worked fairly well but the capsaicin is better. I have gotten this information from the link John gave me to look at. I get a new one every day. I hope this info. helps a little.
