@doctorsdiagnosis: Hickeys are usually harmless, but rare cases have shown they can carry unexpected risks. In 2016, a widely reported case involved a teenager who developed a blood clot after strong suction on the neck, which then traveled to the brain. The neck contains major blood vessels close to the surface, and in very uncommon situations, pressure or trauma in this area can affect circulation and clot formation. These events are extremely rare, but they highlight how sensitive certain anatomical areas are. The takeaway is awareness, not fear. Even common behaviors can interact with the body in ways most people don’t consider.
