If you’ve ever seen a pimple pop… forget it.
This shocking clip shows a giant, infected neck cyst swollen to the size of a tennis ball — and the moment the doctor applies pressure, a thick yellow sac pops out like a balloon ready to burst. Viewers around the world are calling it “the most satisfying but terrifying pop ever.”

But what exactly is happening here? And why does it look so scary?

🦠 What Is This Huge Bulge on the Neck?

Most cases like this are caused by:

✔️ Sebaceous Cyst (Epidermoid Cyst)

A blocked oil gland fills with keratin and pus over weeks or months.
When infected, the area becomes red, swollen, hot, and painful — exactly like the image.

✔️ Abscess Formation

Sometimes bacteria invade the cyst, turning it into a pus-filled abscess that needs urgent medical drainage.

✔️ Keratin Plug / Capsule

The yellow round ball you see is the keratin plug, which must be removed or the cyst will return.

🔥 5 Safety Tips (If You Ever Face Something Like This)

1️⃣ Never Pop a Large Cyst at Home

This can push bacteria deeper and create dangerous infections.

2️⃣ Look for Signs of Infection

Redness, swelling, fever, and extreme pain = Go to a doctor fast.

3️⃣ Keep the Area Clean & Dry

Avoid touching it. Hands carry tons of bacteria.

4️⃣ Warm Compress Works for Smaller Cysts

But NOT for massive or infected ones like this — medical drainage is required.

5️⃣ Always Remove the Cyst Wall

If the doctor doesn’t remove the sac (the “ball”), the cyst 100% comes back.
