"This problem started months ago when she started noticing some numbness to her feet. At first she thought it was related to shoes or socks she was wearing, but the problem continued to progress. The numbness gave way to sharp, stabbing pains, often like an ice pick was being driven into her foot. But the intermittent numbness and pain were only part of the story, because burning, electrical shocks and increased discomfort was becoming more and more common at night. When she could no longer sleep well at night because of the discomfort, and when she noticed pain even with walking barefoot, it was time to be evaluated."
