Tingling, burning, numbness, or a “pins and needles” sensation in the hands and feet can be uncomfortable—especially when it becomes more noticeable at night. These symptoms are sometimes associated with peripheral neuropathy, a condition involving damage or dysfunction of nerves outside the brain and spinal cord.
B6 is involved in neurotransmitter production and normal nervous-system function.
However, this vitamin has an important catch:
Too much supplemental vitamin B6 can itself cause peripheral neuropathy.
That means taking large doses in an attempt to treat tingling may actually make nerve symptoms worse.
