i have had - since July-growing symptoms: itching/burning on arms, legs, thorax, face, hands, feetwhich is sporadic. also, very sensitive to cold . Nails are more and more ridged. i am a vegetarian but i eat eggs and yogurt. Been a vegetarian for over 11 years. i am being tested for Hashimoto s disease but i think i may have a vitamin deficiency - like B 12. What do you suggest I get tested for? Been to regular doctors, inclduing general practitioner and dermatologist for many months and asked about the symptoms....all they say is anxiety. It is not anxiety.
