Left-sided abdominal pain?


A few days ago, while masturbating, I suddenly felt sharp pain in my left testicle, but there was no swelling or redness in the scrotum.
In the following days, although the left testicle no longer hurts, it feels heavy and uncomfortable.

More Info


Left testicular pain can be concerning, especially when it occurs suddenly during activities such as masturbation. There are several potential causes for this type of pain, and understanding them can help you determine the best course of action.

One common cause of testicular pain is testicular torsion, which is a medical emergency. This occurs when the spermatic cord becomes twisted, cutting off the blood supply to the testicle. Symptoms typically include sudden, severe pain, swelling, and sometimes nausea. However, since you mentioned that there was no swelling or redness, it may be less likely that torsion is the cause in your case, especially if the pain has subsided.

Another possibility is epididymitis, which is inflammation of the epididymis, the tube that carries sperm from the testicle. This condition can be caused by infections, including sexually transmitted infections, or by trauma. Symptoms often include pain, swelling, and tenderness in the affected testicle. If you notice any discharge or have other symptoms like fever, it would be wise to consult a healthcare provider.

Trauma or strain during masturbation could also lead to temporary pain or discomfort in the testicles. This can happen if there is excessive force or awkward positioning during the act. The sensation of heaviness or dullness you describe could be a residual effect of such trauma.

Varicocele, which is an enlargement of the veins within the scrotum, can also cause a feeling of heaviness or dull pain in the testicles. This condition is often described as feeling like a "bag of worms" and can lead to discomfort, especially after prolonged standing or physical activity. If you suspect this might be the case, a physical examination and possibly an ultrasound can help confirm the diagnosis.

In some cases, referred pain from other areas, such as the lower back or abdomen, can manifest as testicular pain. This is particularly relevant if you have any underlying conditions affecting the spine or pelvis.

Given that your pain has subsided but you still feel a sense of heaviness, it is advisable to monitor your symptoms closely. If the sensation persists, worsens, or if you develop new symptoms (such as swelling, redness, or fever), you should seek medical attention. A healthcare provider can perform a physical examination and may recommend imaging studies like an ultrasound to rule out any serious conditions.

In summary, while the sudden onset of left testicular pain during masturbation can be alarming, it is essential to consider various potential causes. If the pain has resolved but you continue to feel discomfort, it is best to consult a healthcare professional for a thorough evaluation to ensure there are no underlying issues that need to be addressed.
