I have been suffering from white coated tongue since having two illnesses. One involved my sinuses and the other my stomach. I do not suffer from sinus headaches or stuffy nose nor cramping in my stomach now but do have a white and sensitive tongue and slightly sick feel when it gets bad. I can also feel my pulse racing. My blood pressure has increased as well. Is is my nose or my stomach and what can I do? The doctor took a swab of my mouth and nothing abnormal showed. Elizabeg
