Breast zingers, also known as breast zaps or breast tingles, are brief, electric-like sensations or tingling feelings that some women may experience in their breasts. These sensations are often described as sharp, sudden, and fleeting. While the exact cause of breast zingers is not fully understood, they are thought to be related to hormonal changes and increased blood flow in the breast tissue during pregnancy and breastfeeding. Breast zingers are generally considered normal and are not typically a cause for concern.
