Hi everyone. Ive been ill for the last 4 months, ive had headaches, sickness, weakness and ive now got pins and needles in my hands and feet, my left foot has gone slightly numb and my legs feel so weak that i feel like im going to fall over, i also feel a bit dizzy today. My doctor thinks i have a vitamin b12 deficiency. I had blood tests yesterday but dont get the results til friday. Has anyone experienced this ? I just seem to be getting worse every day, i have no strength at all....x
