Suggest Treatment For Persistent Numbness In The Limbs

My hands and feet have become numb and have been that way for about a month and a half. I was first told that I had Carpal Tunnel and then told that my reason for numbness was anxiety. I am unable to stand balanced and at night my hands and feet feel as if they are swelling. I had a blood pressure and diabetic test and they both came back negative. My mouth feels numb and have koss some weight because I really cant eat. HELP
