I had a cocaine relapse on 8/6/2012 and the whole left side of my body turned to pins and needles really bad. The pain went away the same day and I was fine until two weeks later. I started having pins and needles in my toes on the left side of my body. The pins and needles in my toes have gotten a little better, but now I feel it in my legs and the side of my back. I haven't eatin in two days because of stress and I'm scared. Is this a neuropathy?
