Anxiety: symptoms are not a sign of illness, they are the mind's ability to produce the "flight or fight" response which gives rise to many physiological changes include nausea, sob, insomnia, dry mouth, aphasia, tremor and sweating. Depending on the cause of your anxiety symptoms, your health care provider can adjust your medication.

See your dentist for a clinical and visual exam. Also an ENT specialist for your throat, especially if this has been an ongoing problem.
