Can a Hickey Cause a Stroke? Know the Facts and Warning Signs

A kiss on the neck may seem harmless. Usually, a hickey leaves nothing more than a temporary bruise. However, a published medical case has linked a love bite to a serious artery injury and stroke.

Before you panic over a mark on your neck, here's what the evidence actually shows—and which symptoms should never be ignored.

What Is a Hickey?

A hickey is a bruise caused by sucking or biting the skin. Small blood vessels beneath the surface break, leaving discoloration that gradually fades. Most hickeys are superficial injuries that heal with time.

How Could a Love Bite Lead to a Stroke?

The neck contains carotid arteries that supply blood to the brain. In rare circumstances, trauma can injure an artery's inner lining and trigger a blood clot. That clot can restrict blood flow or send fragments toward the brain, causing an ischemic stroke.

This involves an injury to a deeper artery—not simply a surface bruise "traveling" to the brain.

A Documented Case—and an Unconfirmed Viral Story

In November 2010, the New Zealand Medical Journal published a report about a 44-year-old woman who developed weakness in her left arm. Imaging revealed a clot in her right internal carotid artery beneath a love bite. Doctors attributed the clot to the neck injury. Her symptoms resolved after treatment with blood thinners.

She also had lupus and smoked, details often missing from online retellings. A single case report cannot tell us how frequently this complication occurs.

A separate story circulated in 2016 claiming that 17-year-old Julio Macias Gonzalez in Mexico died after a hickey caused a stroke. That explanation remains unconfirmed by publicly available medical documentation. It should not be presented as a proven death caused by a love bite. Contemporary reporting also questioned whether the original accounts could be verified.

Warning Signs: When to Call 911

Whether or not someone has a hickey, watch for sudden:

• Facial drooping.
• Weakness or numbness, especially on one side.
• Trouble speaking or understanding speech.
• Vision changes.
• Dizziness, loss of balance, or difficulty walking.
• A severe, unexplained headache.

Call 911 immediately if any of these symptoms occur—even if they disappear. Note when symptoms started and use an ambulance instead of driving yourself. Outside the United States, call your local emergency number.

Make Comfort and Safety Part of Intimacy

As a practical precaution, avoid forceful suction, hard biting, and pressure on the neck. Talk with your partner about boundaries, including whether either of you wants visible marks, and stop if something hurts.

Avoid scraping or aggressively rubbing a hickey to remove it. These methods can damage the skin without making the bruise disappear.

At MeetPositives, we encourage open conversations about health, comfort, and consent. Caring for a partner includes listening to their boundaries and taking unexpected symptoms seriously.
