When 1 testicle hurts little?

Mild pain in one testicle can be caused by various factors, including minor trauma, infection, or inflammation, such as epididymitis or orchitis. It could also result from a hernia or varicocele. While occasional discomfort may not be serious, persistent or severe pain should be evaluated by a healthcare professional to rule out more serious conditions, such as torsion or tumor. If accompanied by other symptoms like swelling or fever, seek medical attention promptly.
