That is one of my older post when I had intermittent burning on various places on my body. It would appear sporadically on my arms, legs and feet. Never all at once. It usually lasted about a couple of hours or all day. It felt like a sunburn. It came about suddenly when I started taking mega doses of Vitamin B12 per my doctor’s instruction to treat my deficiency. It lasted a couple of months, before it subsided. Then it stopped and I don’t get it anymore.

I do still a quarter size spot on my right foot that will intermittently burn in waves. It’s different from the sunburn like sensation I got as described above. It usually does it for 1-2 minutes and stops. It’s not bothersome enough to take meds for. Hope that helps.
