HERO - Trigger point self-care-shoulder joint edition-: You can treat the cause of pain trigger point by yourself!

Thank you for picking up this book.

Do you all know the word trigger point? ?

There are many cases where this trigger point is actually the cause of common pain and those for which the cause is not well understood.

A trigger point is, so to speak, an induration of a muscle, which causes various symptoms depending on the site where the trigger point is created.

Symptoms range from headache to low back pain, arthritis and other joint pains, dizziness, nausea and chest pain, posture collapse, muscle weakness and swelling.

The troublesome point of the trigger point is that the symptom appears at a distance from the place where the trigger point occurred, which is called referred pain.

This can cause indefinite complaints such as pain, numbness, and heaviness in a very wide area of what is created in one place.

If you currently have some symptoms and there is no particular change even if you are prescribed medicine, it is possible that the trigger point is involved as a direct cause.

Painkillers are, so to speak, symptomatic treatments, and the cause remains the same, but they only relieve the symptom of "pain."

In this book, we will also touch on trigger points that can be the cause of various pains, actual treatments, and simple self-care methods that you can do yourself. I made it so that you can treat yourself while actually using your own body, so please read it.

What is a trigger point?

What is a trigger point in the first place? It is said to be "in the chordal induration that is touched on the muscle tissue, where you feel sharp pain when you press it.

" A cord-like induration is a band of muscles that is stiff like a cable, and it means that there is a trigger point in the band of stiff muscles.

For example, there is a quadriceps muscle on the front of the thigh.

If you put your thumb on your thigh and slide it left and right while applying pressure, most people will feel that something that looks like a muscular band hits.

This hard band is a cord-like induration, and the trigger point is inside it.

Normally, muscle fibers are stretched with approximately equal tension in all parts.

However, when a trigger point is formed, only the hardened part contracts extremely. As a result, the surrounding normal muscle fibers are overstretched.

At areas where muscle fibers are extremely contracted, such as trigger points, blood flow is reduced, resulting in oxygen deficiency and accumulation of waste products, which promotes pain.

If you compare it with a rubber band, it may be easier to understand if you imagine the part that is tied up and lumped as a trigger point.

The actual muscle fibers are not tied up, but the lumps do not move much even if pulled, but the surrounding rubber stretches by that much.

In the treatment of the trigger point, if you loosen the dense part of B in the figure AB below, the surrounding muscle fibers can also return to the uniform tension like A.

A Normal muscle fibers

B Muscle fibers with trigger points formed

Trigger points are often found in multiple places within the same muscle fiber, but among them, there is a trigger point that is the cause, and it is called a central trigger point.

And what is formed in other places derived from the induration that was made at the beginning is called a satellite trigger point.

If the central trigger point is treated properly, the satellite trigger point created from it will also have no cause, so it will improve and disappear over time.

Conversely, if the satellite trigger point is treated and the root cause of the central trigger point is not eliminated, it will relapse over time.
