Hi all, I haven't been on this forum for ages because the PN in my foot went away with my mega doses of B12! I started with 1000mcg, then upped to 2000mcg. I went through the improvement/worsening cycles and then had many pain-free months! yea! Until last weekend when I got a sharp stabbing pain in my foot. After a couple of times I decided to increase my B12 once again. I've had a few more instances of the pain. Does this mean my body is still recovering? Or is something flaring? ... and looking for the scratch my head smilie.
