hey. Im a 24 female and have been having pins and needles in my right leg, numbness, very weak for about 3 weeks now, about a week ago i had pain in my right leg also, to the point where it was hard for me to walk. I went to the doctor ad had an ultrasound on my right leg, blot clot was rulled out. Today, my left cheek went pins and needles, now my back, around my spine area and back of neck is pins and needles, what do you think this could be? Im feel like their is something serious happening to me and since 3 weeks ago, it has progressed rapidly
