What do you do if your balls are black and blue?

If you notice that your testicles are black and blue, it may indicate bruising or trauma, and it's important to seek medical attention promptly. This could be a sign of an injury, infection, or other underlying condition that requires evaluation by a healthcare professional. Avoid any self-diagnosis or treatment until a doctor has assessed the situation. In the meantime, rest and avoid any activities that may exacerbate the condition.
