altered sensation with nerves

Hi, i first become aware of a alter feeling on the back of my left forearm in November 2011. Since then it's progressed to both arms, legs, neck and face. It's like an altered sensation with my nerves (as i still have feelings) but at times they burn and tingle. My elbows and knees are cold and slightly numb. Headaches and anxiety have increased. I'm booked in to see a specialist regarding my nerves. Just trying to stay postive, meditating and resting most days.
