Headaches may have different causes, and 99,5% of them are benign, that is, offers no life risks whatsoever.

Common causes:

1. Caused or aggravated by specific neck movements;
2. Stress, or end of a stressful situation;
3. Physical activities;
4. Hormonal alterations (period, pre-menstrual syndrome, puberty or menopause);
5. Blood glucose alterations (excess or low blood sugar);
6. Specific foods (cheese, chocolate, coffee and others).

Headache may vary in location and characteristics. Some present as a pressure in the entire head, others as a throb, occasionally causing nausea and vomit associated to intolerance to light and noise.

Some of these causes makes muscular spasms. This happens because some muscles are located in bone structures near the joints, which may cause joint misalignment that restrict movement, making it painful. Thus, neck movements can aggravate or trigger headache in that situation.
