How You Get Chronic Tension Headaches
And How to Get Rid of Them
1. You get tight muscles and muscle spasms in your neck, shoulders and/or upper back from poor posture (or from an injury)
Poor posture is often a byproduct of your job, like sitting at a computer terminal all day or stooping over a work station.
Working all day in poor posture causes tightness.
The constant strain from the poor posture causes microscopic muscle fibers within the tight muscles to tear.
Your body tries to prevent this tearing by causing the muscles to knot up, or spasm.
The constant strain on your neck/shoulder/upper back muscles from continual poor posture causes microscopic muscle fibers within the spasms to tear.
Eventually these tears heal.
As a result of that healing, microscopic threads of scar tissue are left behind in your spasms.
These scar tissues lock your spasms into place, preventing them from being able to relax.
2. These tight muscles and muscle spasms cause tension headaches
These muscle spasms restrict blood flow to the back of your head by clamping down on arteries (it's like stepping on a turned-on garden hose).
These spasms also irritate nerve endings.
This blood flow restriction and nerve ending irritation cause tension headaches.
3. You develop more and more muscle spasms
The constant strain from poor posture causes more tightness and spasms.
The constant strain from poor posture causes more tearing within the tight muscles and spasms.
The continual tearing and healing of microscopic muscle fibers within the spasms causes the formation of more scar tissue.
This additional scar tissue within the spasms prevents the them from being able to relax.
The additional spasms - which can't relax due to the scar tissues within them - cause more blood flow restriction to the back of your head and more nerve ending irritation.
This additional nerve ending irritation and blood flow restriction causes your tension headaches to become chronic.
