Headaches and migraines can also be triggered by hormonal changes in women, and food allergies.
Determining the causes of headaches, and migraines is a complicated matter, and there are not a lot of established medical facts.
While talking to one headache specialist, he looked at us, and said if G_D would give him the answer he would know what to do.
I respected that answer.
Unlike tension headaches, migraines, and cluster headaches are vascular because of the constriction, and expansion of the arteries of the head.
Putting pressure on the nerves causes pain.
Here is the theory behind migraines.
They begin when blood vessels in the brain contract, and expand inappropriately.
This may start in the occipital lobe "my wife has had nerve blocks in the occipital nerve", in the back of the brain, as arteries spasm.
The reduced flow of blood from the occipital lobe triggers the aura that some migraine sufferers experience.
When the constriction stops, and the blood vessels dilate, they become too wide.
The once solid walls of the blood vessels become permeable, and some fluid leaks out. This leakage is recognized by pain receptors in the blood vessels of surrounding tissue.
In response, the body supplies the area with chemicals which cause inflammation.
With each heart beat, blood passes through this sensitive area causing a throb of pain.
When something triggers changes in the brain, these changes cause serotonin to be released, and blood vessels constrict, and dilate.
Headaches are different from migraines in that they are caused by a disturbance of the pain-sensitive structures in the head.
Several areas of the head, and neck have the pain sensitive structures.
They are divided within the cranium blood vessels, meninges, and the cranial nerves, and outside the cranium which is the muscles, nerves, arteries and veins, subcutaneous tissues, eyes, ears, sinuses, and mucous membranes.
Most headaches respond to simple painkillers. So headaches and migraines will have to be treated separately to find relief.
Migraines will need something stronger than mild pain pills to have you back on your feet, such as triptans.
After reading this you can see how closely headaches and migraines are related. It's kind of like walking a tightrope.
Wishing you a headache, and migraine pain free day.
