Why Your Shoulder Pops, Clicks, or Grinds

Have you ever moved your shoulder and heard:

👉 A pop
👉 A click
👉 A grinding sound

It can feel strange and sometimes concerning.

But shoulder noise is actually very common.

Why Shoulders Make Noise

Your shoulder is one of the most mobile joints in the body.

That mobility means:

• Many muscles and tendons move around the joint
• Structures glide over each other constantly
• Small shifts can create sound or sensation

Common Causes of Shoulder Popping or Clicking

1️⃣ Tendons Moving Over Bone

As you rotate or lift your arm:

👉 Tendons can shift slightly and “snap” back into place.

This is one of the most common causes of clicking.

2️⃣ Gas Bubbles in the Joint

Just like knuckle cracking:

• Small gas bubbles form in joint fluid
• They release during movement

👉 Creating a popping sound.

3️⃣ Inflammation or Irritation

If tissues inside the shoulder are irritated:

• Movement becomes less smooth
• Friction increases
• Sounds become more noticeable

4️⃣ Cartilage or Joint Changes

As the joint changes over time:

• Surfaces may become rougher
• Movement can feel or sound “grindy”

When Shoulder Noise Is Usually Harmless

If your shoulder:

• Pops without pain
• Moves normally
• Feels stable

👉 It’s often nothing serious.

When It May Matter More

Pay closer attention if the noise comes with:

🚩 Pain
🚩 Weakness
🚩 Limited motion
🚩 Catching or instability

That combination may signal irritation inside the joint.

The Takeaway

Shoulder popping or clicking is very common and often harmless.

👉 The important thing isn’t the sound, it’s whether symptoms come with it.

At Buffalo Arthritis & Joint Pain Center, we help patients explore non-surgical options designed to improve shoulder comfort and movement.

👉 Not every pop means something is damaged.
