The act of planting strawberries, also known as making hickeys, is not seriously harmful and may only affect local blood circulation or appearance. However, the distribution of the carotid artery on the neck is relatively fragile, so when the suction force is too great when planting strawberries on the neck, it may lead to rupture of the carotid artery or stroke, but such cases are extremely rare, so patients generally do not need to worry too much: 1. Local bruising: generally the strawberries on the neck are caused by the suction force and the rupture of local capillaries causing bleeding. Normal human blood vessels have certain elasticity and self-healing, after the appearance of strawberries, the main symptom of local bruising, may appear strawberry-like red-purple bruising, but over time can be gradually absorbed by the body, and then gradually recede; 2, carotid artery ischemia: when the strawberry planted in the neck involves the carotid artery, because the blood in the carotid artery mainly supplies the cerebral hemisphere, planting strawberries when the suction force is too large, may lead to Ischemia and hypoxia in the brain, causing dizziness, headache and various brain dysfunctions; 3. Carotid artery rupture: If the carotid artery is relatively fragile, or if there is a local lesion of the neck vessels, etc., the strong suction force when planting strawberries may cause the carotid artery to rupture. If the bleeding is severe, it may lead to thrombosis, which in turn may cause cerebral thrombosis, but it is very rare.
