My legs hurt from knees down. I m on my feet most of the day, however, I ve been having shooting pains (not muscle cramps) in my feet at night which wake me from sleep. I ve had blood tests and I m not diabetic. Often the back lower part of my legs hurt. Yes, I m overweight, but these symptoms have suddenly happened in the last 2 months. Any ideas of what it could be? I m scheduled for a sonogram, but that s 2 weeks away.
