Chest Pressure, Costochondritis and Restricted Breathing: Sternal Decompression
This modality teaches the Sternal Decompression Technique, which releases the muscles attached to the sternum and anterior ribs. When these muscles enter spasm, they can restrict rib movement and create pressure across the chest.
Modality 08 · Releases: Chest pressure / non-cardiac chest pain · Costochondritis · Shallow or restricted breathing · Anterior rib cage tightness · Difficulty relaxing · Fatigue
Step 1
Understanding the Problem
The sternum is the central anchor of the front of the rib cage. Prolonged stress, shallow breathing and overactive accessory breathing muscles pull the muscles attached to the sternum and ribs into a spasm that does not let go. The chest feels held, the ribs stop expanding, breathing goes shallow, and the pressure across the front of the chest can be frightening enough to send people to the emergency room, where the heart is found to be fine. Releasology decompresses the sternum by releasing the muscles compressing it, so the rib cage opens and the chest can finally relax.
What this release relieves
- Chest pressure and non-cardiac chest pain. Once the heart has been cleared, the pressure that remains is the muscles across the sternum and ribs in spasm. It releases when they do.
- Costochondritis and pain where the ribs meet the breastbone. The rib-sternum joints are inflamed because muscles are pulling on them all day. Take the pull off and the joints settle.
- Shallow, restricted breathing. A compressed rib cage cannot expand. Clients feel the breath widen into the chest as the sternum releases.
- Tightness across the front of the rib cage and difficulty relaxing. The sense of being held in the chest is muscular guarding; it is one of the first things to change.
- Fatigue and generalised weakness. Breathing against a compressed chest is exhausting; energy returns when it stops.
- Sympathetic nerve irritation affecting the heart's rhythm. The sympathetic chain runs along the inside of the rib cage. Clients describe palpitations and a racing heart settling as the compression comes off; cardiac symptoms should always be evaluated by a physician first.
The sternum is the central anchor of the anterior rib cage.
It is not a muscle, but it is directly influenced by multiple layers of tissue that attach to it, including:
• pectoralis major and minor
• intercostals
• pericardium
• diaphragm
• serratus anterior
• subscapularis (Heart 1 point)
When tension accumulates in these structures, the sternum becomes restricted in its natural movement.
Clients often experience:
• a feeling of pressure in the chest
• shallow or restricted breathing
• tightness across the anterior rib cage
• difficulty fully relaxing
This is not always perceived as pain.
It is often felt as compression or holding in the chest, can give the sense of overall weakness and can weaken the heart and pericardium over time.
Frequently asked questions
My cardiac workup was normal but my chest still hurts. Why?
Because the pain is coming from the muscles and joints of the chest wall, not the heart. That is a common finding, and it is exactly what this release addresses.
How is this different from stretching the chest?
A stretch pulls against a muscle in spasm. Releasology releases the spasm at the muscle, so the rib cage opens without force.
Does this help with anxiety-type chest tightness?
Chest tightness under stress is the accessory breathing muscles and the sternal attachments in spasm. Releasing them changes the breathing pattern, and clients describe the sense of pressure lifting.
Step 2
The Clinical Problem
Spasm of the muscles attached to the ribcage can distort the space around the heart and pinch its nerve supply.
A client reports pressure across the chest, shallow breathing, or tightness near the sternum.
In some cases the discomfort may mimic cardiac symptoms even though the heart is healthy, or these spasms by pinching the sympathetic nerves that pass to the heart from the upper thoracic spine become pinched and cause heart function problems.
The source often lies in the muscles attached to the sternum and ribs, which can restrict normal rib movement when they enter spasm.
This restriction can reduce chest expansion and alter breathing mechanics.
Release these muscles to decompress the chest and for a healthy heart.
Step 3
Why This Happens
The anterior chest is highly responsive to both:
• physical tension
• emotional and stress-related states
Muscles attaching to the sternum are constantly active in:
• breathing
• posture
• protective responses
When the system is under prolonged stress:
• breathing becomes shallow
• accessory muscles become overactive
• the rib cage loses its ability to expand fully
Over time, this leads to:
• reduced mobility between ribs
• increased tension across the sternum
• a loss of elasticity in the tissue
From a Releasology perspective:
this creates a disruption in conduction through the central thoracic region.
Instead of movement and expansion:
👉 the system holds and compresses
Prana, which should move freely through the chest, becomes restricted.
