Why have my legs and feet become EXTREMELY sensitive to light touch and hot and cold temperatures?

Saw this on Dr. House. It's called Allodynia. I remember him asking to check calcium levels and a couple of other things I can't remember. If you haven't checked B12 and other causes of neuropathy, it may be worth it. Anticonvulsants like Lycria can help with the pain if you don't find a cause.
