Pain when rubbing the scrotum and testicles can be caused by a variety of reasons, including but not limited to physiological factors, trauma, and infection. This pain may manifest as dull pain, stabbing pain, or severe pain, and its duration can range from short-term to long-term.

Physiological factors can be one of the causes of pain. For example, standing or sitting for long periods, especially in hot environments, can cause the temperature inside the scrotum to rise, thus triggering pain. Excessive or strenuous exercise can also cause pain in the testicular area. If the pain worsens after meals or upon waking in the morning, it may be related to body posture or blood circulation.

Another possibility is related to trauma or injury. For example, a collision or fall during sports can injure the testicles, causing pain. Certain sexual activities or improper physical activity can also injure the testicles, leading to pain. If the pain is accompanied by swelling, bruising, or changes in skin color, it may indicate trauma.

If symptoms include persistent pain, swelling, or accompanied by fever, nausea, or other symptoms, an infection such as epididymitis or orchitis should be considered. These conditions require prompt medical attention to avoid potentially serious consequences.
