I am 70 years old, I am not diabetic. For the past several months I ve noticed a numbness on tips of both of my great toes. In addition I notice some discomfort (like my shoes are too tight on my toes), in fact I now much prefer open toed sandals. No sign of hammer toes, but arches have fallen, and it s now difficult to find comfortable shoes. What is going on with me? I m otherwise very healthy, but do need to get more exercise. Thanks, Allan
