Vague: I would see a Dr. and discuss your issues and symptoms. Headaches can be caused by a number of factors- stress, grinding of teeth at night, or clenching during the day, allergies, etc. You really should see a Dr. to be evaluated

Bruxism: Bruxism (grinding or clenching) is common at night and results in at night and morning headache. See an oral surgeon for assessment. This is in the spectrum of TMD (temporomandibular joint disorders).

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 heart palpitations, nausea, tingling, insomnia, dry mouth, speech impairment, tremor and sweating. Depending on the cause of your anxiety symptoms, your health care provider can provide you with treatment option
