Blood sugar problems and nerve problems, which often go hand in hand, are just a few things that can cause tingling in your limbs. This is a stretch though based on your problem, but see a doctor anyway. I had tingling and numbness in my little and next toe. It turned out to be some bulging discs in my back. See a Neurosurgon, or Neurologist and get a MRI.
