Do you feel a sharp, sudden, stabbing pain in your shoulder when you try to reach for a high shelf in the kitchen, put on your shirt in the morning, or hit a powerful overhead smash on the Padel court? Perhaps this deep, nagging ache even wakes you up from a deep sleep the moment you roll over onto your affected side.

Many patients rush to take painkillers or even consider cortisone injections, terrified that they have suffered a severe “tear.” But in reality, the vast majority of these cases come down to a purely mechanical issue known medically as Shoulder Impingement Syndrome.

At Rikaz Chiropractic Clinic in Jeddah, we see daily how a simple movement dysfunction in the back and shoulder can spiral into a debilitating daily struggle. Let us explain the engineering of your shoulder joint, why your tendons are getting pinched, and how we provide root-cause shoulder impingement treatment without surgery or medication.

The shoulder is the most mobile joint in the human body, but it pays a heavy tax for this flexibility by being highly susceptible to instability.

Shoulder impingement does not happen by accident. There are two main mechanical reasons why your bones are suddenly grinding against your tendons:

Remember the Upper Cross Syndrome we discussed previously? When you sit for hours with your shoulders rolled forward, the mechanical position of your “shoulder blade” (Scapula) changes. This forward slump literally tilts the bony roof of the tunnel downward, closing off the space for your tendons. If you try to lift your arm while your back is hunched, you are physically grinding your own tendons!

Racquet sports like Padel and tennis, swimming, or CrossFit exercises that require heavy overhead lifting are prime suspects. These rapid, repetitive overhead motions—especially if performed with poor technique or while the muscles are fatigued—cause the tendons themselves to swell. A swollen tendon becomes thicker, making it much more likely to get jammed inside the narrow bony tunnel.

How do you know your pain is a mechanical impingement and not just a standard muscle strain? Look for these classic signs:

1. The Painful Arc: You feel no pain when your arm is resting by your side, and no pain when your arm is pointing straight up at the sky. The pain appears suddenly and peaks only in the middle range (when lifting your arm between a 60 to 120-degree angle).
2. Agonizing Night Pain: You absolutely cannot sleep on the affected side, and you often feel a deep, throbbing ache that wakes you up if your shoulder moves during the night.
3. Weakness When Reaching Backward: You experience a sharp catch and severe difficulty if you try to reach into your back pocket or, for women, when trying to unhook a bra from the back.

In biomechanics, lifting your arm overhead is not the job of the shoulder joint alone. The real secret lies in the large, triangular bone on your back: the Scapula (Shoulder Blade).

The engineering rule states: every time you lift your arm, your shoulder blade must rotate upward to open the bony tunnel and let the tendons pass safely. However, due to poor posture or muscle fatigue, the shoulder blade often gets locked in place and loses its ability to rotate (a condition called Scapular Dyskinesis).

The result? When you forcefully lift your arm, the arm bone crashes directly into the roof of the shoulder because the scapula didn’t move out of the way, grinding the tendon between the two bones with every swing!

Many patients simply decide to stop using their affected arm, avoiding lifting it to escape the pain, believing the issue will magically fade with time. This neglect opens the door to far worse complications:

1. Rotator Cuff Tear: The constant friction of the tendon against the bone is exactly like rubbing a rope against a sharp rock. Over time, the tendon fibers fray and eventually tear partially or completely, turning a simple mechanical inflammation into a severe injury requiring complex surgery.
2. Frozen Shoulder (Adhesive Capsulitis): When you stop moving your shoulder due to pain, the joint capsule begins to shrink, stiffen, and form adhesions. Suddenly, you find yourself completely unable to move your arm in any direction (even if someone else tries to lift it for you), and recovering from this agonizing condition can take many painful months.

If you are suffering from shoulder impingement, your first instinct might be to aggressively “stretch” the shoulder by forcing your arm overhead or hanging from a pull-up bar or doorframe. Stop doing this immediately! These movements only increase the grinding of the already inflamed tendons.

Instead of lifting your arm, let gravity open the joint for you:

Injecting painkillers into the shoulder might hide the pain for a few days, but it does not open the collapsed “bony tunnel.” To fix the problem permanently, the biomechanics of both the shoulder and the upper back must be corrected.

At Rikaz Clinic, our shoulder impingement treatment plan is highly structural and comprehensive:

The shoulder is a highly complex joint, and treating it requires an expert who understands the body’s entire kinetic chain.

Led by Dr. Mohammad Yashar, who underwent 5 years of rigorous academic and clinical training at the prestigious RMIT University in Melbourne, Australia, we perform specialized orthopedic tests (like the Neer Test and Hawkins-Kennedy Test). These tests precisely isolate the affected tendons and rule out complete tears before any manual treatment begins.
