Crux thank you so much for telling me that!!! You are the first person to tell me or that I have read anywhere that has a serum above 3000!!!!!! That number was scaring me since nobody else seemed to have one that high. I even read somewhere else that some of the tests dont go above 2000! Crux would you share your story with me??? You say you have a numb spot on your heel...did it hurt when you stretched the skin, either by standing up to walk or rotating your foot????? Did you get feeling back???? Since your story seems similar to mine Im curious. thank you for sharing!
