For the past year I have been experiencing dry peeling lips that sometimes itch feel sore and burn really dry mouth and throat raised little yellow painless spots inside cheeks and lower lip whitish coating on tongue itchy nose and dry cough this all started when I was pregnant I have seen many docs who haven't been able to diagnose me I am really frustrated with it and seems my boyfriend and daughter have the same thing any ideas what this could be? Would be very grateful!
