Hi, i have tingles in my cheeks and hands, tingles and numbness in my back between shoulder blades that come and go, but i have constant tingling in my lower leg as soon as i stand with burning in my outer calf, when i walk a short distance, i starting to get very worried as this is causing me extreme pain. Ive been referred to an neurologist but app isnt for months, should i be worried? What do you think could be causing it? Please help :(
