Why i do have headache every time i woke up late from sleep ?

Possible Bruxism: Waking up with headaches is a common symptom of bruxism, which is grinding or clenching your teeth at night. This is not always something that a partner will hear you doing and usually most people aren't aware they are doing it. Bruxism can be very destructive to your teeth, jaw muscles and TMJ (jaw joint). A proper diagnosis and effective treatment can be achieved from a highly trained dentist.

TMJ !!: Most likely you are clenching and/or grinding your teeth, and your jaw and facial muscles in spasms may be triggering your headaches. Get evaluated by a dentist or physician asap to get on the road to recovery !

TMJ, sleep disorder: 2 most common possibilities. TMJ disorder or sleep apnea. Start with your MD. If negative for sleep apnea, see a TMJ expert. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask your MD, your dentist and your dental society for referrals.
