I've been experiencing an increase in foot pain and burning since early December, but the last couple of days, my toes have been burning constantly and they only let up for a matter of minutes sometimes and then escalate back to a higher level of discomfort. Is this normal for PN to act like this? Prior to this I seemed to stay at the same level of pain and numbness but I've also noticed an increase in the numbness. I probably shouldn't ask if its normal, but I'm hoping you understand what I mean by that, maybe it would be best to say is this a flare up, I don't know.
