Recently I have been experiencing, what I can best describe as numbness on the bottom of my right foot around the area of the front of the foot (proxomal to the toes). At first I kept on taking off my shoe because I thought that my sock was bunching up, but then I realized that it was my foot. There is no pain involved and the sensation can be described as feeling like I'm walking on a bunched up sock in that part of my foot. No swelling, no pain, no masses noted...any suggestions. p.s. I do exercise a good deal (running and eliptical). Thanks in advance.
