The Bottom Of My Feet Are Sore To The Touch And Also Feel Like I Am Walking On Nails Or Glass If I Stand For Any Length Of Time. My Calves Are Also Tender When I Stand For A Long Time?

I have the same problem.  When I asked the doctor he said it is probably because there are many nerve endings in our feet; and the pain is a result of supporting the body weight all day.  When I told him that I wake up with foot pain...he basically said it's because I'm not sleeping well so my body is not recovering from the foot pain.   I hope this helps.
