Post Date: 2/9/12 2:05 pm I have been having lower leg cramps on and off for about two weeks. Yesterday I felt dizzy like fainting, my arms and legs went numb, my fingers clenched by themselves super tight and I was unable to move them to release the tightness, then I fainted. The hospital said it was dehydration and released me. My doctor took a lot of blood and I am awaiting the lab results. Does anyone recognize these symptoms as a possible minerals/vitamins deficiency? I would appreciate any input.
