Many different things can lead to a person having a headache, especially a dull one that is constant and chronic.
A dull headache is not a migraine, but such headaches could develop into the migraines later.
One possible cause for such headaches is anemia. This is when the red blood cells are damaged or their count is low within the bloodstream. When this occurs, there is less oxygen going to the brain, and with less oxygen come headaches.
When low levels of oxygen are coming to the brain, the damage being done can be seen on an MRI, and if a person believes that this is the case, the best thing to do is see a doctor immediately.
Hypothyroidism can be another problem. Low thyroid production can lead to a dull headache, and it can also lead to migraines. Some of the symptoms of this condition are depression, weight gain, cold intolerance and fatigue, and it can run in the family as well.
When the blood sugar level is low it can result in hypoglycemia, which also causes headaches. However, this is fairly easily preventable. It is important to eat regularly, and it is especially important to eat breakfast, because not eating will provoke headaches, especially in cases where the head has already become sensitive to such pains occurring on a regular basis.
In these cases it can also become more severe and eventually lead to excruciating migraines.
When a person has very high blood pressure, there can be a throbbing and pounding sensation in the head, and it is important to remember that if someone has uncontrolled hypertension, they cannot be taking migraine medication such as triptans.
Dull headaches can also be caused by infections that often come with the common cold or flu.
Sometimes if people are having constant post viral headaches they can take a two-week course of steroids that will help to alleviate the condition.
Some types of headaches can be associated with autoimmune diseases as well.
Conditions such as lupus, multiple sclerosis and Hashimoto’s thyroiditis can all lead to headaches.
Sometimes, when a person has had a surgery, they can experience chronic headaches during the recovery process. Usually the doctor will dismiss the pain as being normal, but if it lasts for a longer period of time, the person needs to go get it checked out, because many people have developed migraines as a result of surgical procedures.
