I can deal with the burning and numbness during the day. I take 400 mg. of Gabapentin at bedtime and 25 mg. of Amitriptyline and 1000 mg. of aspirin. This seems to work ok most of the time but if the burning in my feet is bad at bedtime I use Aspercream with 4% Lidocaine. That helps me get some sleep. Good luck.
I also have Erythromelalgia and Raynaud's
So My feet are either red, ho and swollen or purplish blue and cold. '
