I was diagnosed with B12 deficiency. I took injections and now still take sublingual tablets 3 times per week. Level in my blood is now in good range, but my neurologist says that just the amount in your blood, not your body.

The injections in the feet relive some of the pain. After getting them, I found that the frequency of my painful attacks were less, and a bit more tolerable. I'm aware there is no cure for feet neuropathy.
