Headaches have a number of causes, ranging from eyestrain, sinus inflammation to life-threatening conditions such as encephalitis, brain cancer and cerebral aneurysms. When the headache occurs after a head injury the cause is usually quite evident .
Other causes are- dilation of the blood vessels in the head, brain swelling, involvement or inflammation of specific nerves of the face, stressful occurrences, menstrual phases, food triggers, or medication.
Tension headaches are the most common type of headache and occur due to contraction (tightness) of the muscles in shoulders, neck, scalp, and jaw. They are most often caused by stress, depression, or anxiety. Excess work load, lack of sleep, missed meals, and use of alcohol or non prescription medication makes a person more susceptible to tension headaches. Some foods can trigger a headache. These include chocolate, cheese, and monosodium glutamate (MSG), a flavor enhancer and Caffeine. Other common reasons that aggravate a tension headache are- holding the head in one position for a long time (like using a computer, microscope, or typewriter), sleeping in cold temperatures or abnormal posture while sleeping, clenching of jaws or teeth grinding.
Another type of headaches is Migraine headaches. They are severe and recurrent headaches and are generally accompanied by other symptoms like visual disturbances or nausea, are mostly unilateral but may spread to both sides. They are associated with an "aura" (warning symptoms that start before headache).They are felt as a throbbing, pounding, or pulsating pain.
Another less common type is Cluster headaches that are stabbing or sharp, extremely painful headaches, tend to occur several times a day for months continuously and may then go away for some period of time.
I do not know from your post what is the nature of your headaches but I feel they could be tension headaches because they are persistent and without any associated acute symptoms. Since doctors have not been able to find out a cause, there seems to be no pathology in brain. Have you had a CT scan or MRI of brain? If no, please go for any one and consult a neurologist.
As a general rule, please make some lifestyle changes that may help. Please take a good sleep at night, a diet rich in fruits and vegetables( they are rich in multivitamins and multiminerals), avoid fast food and preserved food, exercise regularly and keep yourself free from stress. Relaxation techniques help a lot in relieving the symptoms. Please consult a neurologist, and psychotherapist if stress is the cause. Hope this helps you. Take care and regards!
These are the exercises and relaxation techniques to help with headache.
