What causes the headache?

By definition, headache is the pain we suffer in the head, face, and sometimes in the upper part of the neck.

In the skin, bones, eyes, ears, mouth and nose we have pain-sensitive structures. The brain itself is not sensitive to pain, so the brain is not responsible for headaches.

Normal headaches are felt on both sides of the head and cause tension or muscle contractions. Tensions and contractions usually occur in the neck and chewing muscles, but this type of headaches do not give excessive work: they take some analgesic.

At the same time, the veins of the head are also very painful. In fact, cerebral veins are the source of the annoying migraines that some people suffer. In these cases, the pain occurs on one side of the head or behind an eye.

The way migraine occurs is not known; all theories point to the fact that the key is in the relationship between the nerves and the veins, but the concrete mechanism is still to be understood. However, new research places the source of migraines in the electrical failures of the brain.

This trend is typical of those who suffer migraines, but there are eleven factors that can trigger headache: stress, very strong light, noise, certain odors, certain types of cheese, chocolate, wine... Migraines cause great discomfort and once started, you have to take specific medicines to end the pain.
