I had the same thing occur but only once. Stood up from my favorite recliner and left foot would not move. I'm telling it to move and nothing... I picked it up and move it manually and after a mintue or so it finally started functioning normally again.
I take 3600mg of Gabapentin and 30mg of cymbalta daily, with 5000 IU of B-12 orally.
I still have burning, mostly at night and general feet pain, sometimes excruciating and other times just annoying.
Still trying to get better......
