Left testicle pain when walking is most often caused by a varicocele (enlarged veins in the scrotum), a hydrocele (fluid buildup around the testicle), or an inguinal hernia. However, other important causes include epididymitis, testicular torsion, kidney stones, muscle strain, or referred pain from the lower back or groin. Because some causes—like testicular torsion—are medical emergencies, identifying the source of your pain quickly matters.
The fastest way to narrow down what may be causing your discomfort is to take a free, instant, online symptom check. In just a few minutes, you can better understand possible causes based on your specific symptoms and get clear guidance on your next steps—whether that's self-care, seeing a doctor, or seeking urgent care. Don't guess when clarity is one click away.

Here are some common conditions that can cause left testicle pain while walking:
These conditions lead to increased pain with walking because movement and physical activity put extra pressure on the affected areas. The motion of walking can stretch or compress sensitive tissues, leading to increased discomfort. Additionally, gravity's effect while walking can cause more blood flow to the area, potentially worsening symptoms like swelling or pain.
Less common causes of testicular pain with walking are epididymitis (inflammation of the tube that carries sperm), testicular torsion (twisting of the testicle), and certain autoimmune conditions that affect the testicles. Some medications may also cause testicular discomfort as a side effect.
Because multiple conditions can cause similar symptoms, you can use Ubie's free AI symptom checker to help identify potential causes of your pain before consulting with a healthcare provider who can examine you, ask detailed questions, and if needed, carry out tests to find the exact cause. If pain is severe, you should be evaluated by a healthcare provider immediately.
