Chronic headaches, also known as chronic daily headaches, are headaches experienced 15 or more days each month for more than three months duration. Chronic headaches can be different types of headache subtypes, including migraines, tension headaches and hemicrania continua headaches.
Chronic Headaches
Prognosis
Due to the consistency of having headaches, chronic headaches can be very disabling, requiring lots of time taken off work and responsibilities. Having chronic headaches is also likely to increase the risk of certain mental health problems, such as depression, anxiety, and sleep problems. If the headaches are caused by an underlying condition, treatment of this should relieve the headaches. However, if there is no underlying condition, treatment focuses on relieving pain.
What are the symptoms?
Grinding or clenching teeth can put pressure on the oral structure: muscles, tissues, and jaw. This pressure translates into:
- anxiety, stress, and tension
- earache, as some temporomandibular joint structures are close to the outer ear canal. The pain may not be directly in the ear, it may be referred pain from a nearby area
- eating disorders
- headache
- muscle sensitivity, especially in the morning
- dental sensitivity when consuming hot, cold, or sweet foods
- insomnia
- jaw pain or swelling
These are general symptoms, although some people may grind and clench their teeth but show no symptoms. Things that can affect how long the clenching lasts include: patient stress levels, teeth not being aligned, posture, diet, and sleeping habits.
