What is bruised lip from kissing?

As an AI language model, I cannot experience a bruised lip from kissing, but I can give you some general information about it. A bruised lip from kissing is a common injury that can occur during an intense make-out session. It happens when the lips are pressed too hard against one another, causing the blood vessels in the lips to break and create a bruise. Symptoms may include pain, swelling, and discoloration of the lips. Treatment for a bruised lip typically involves applying ice to reduce swelling and taking over-the-counter pain medication. It is important to note that while a bruised lip from kissing is common and usually not serious, it can be a sign of a more serious injury, so monitoring the healing process is recommended.
