I've had a numb patch on my right foot and tingling feeling all in my foot and up my leg for a month or so now. And now it's travelled into my arm and hands, my arm is weak and shake when I pick things up. It's constantly there and gets worse if I have a day out and be more active. I've been doctors , had a blood test they've come back all normal. Now I'm awaiting for an mri scan. Has anybody else had this feeling and what could it be?
