I'm sorry to hear about the pain you're experiencing in your left testis and leg. Pain in the testis that radiates to the leg can be caused by several conditions, such as nerve irritation, inflammation, or issues related to blood flow. One common cause is nerve compression or referred pain from the lower back or groin area, which can affect both the testis and the leg.

Since testicular pain can sometimes indicate serious conditions like infections, testicular torsion (twisting of the spermatic cord), or varicocele, it is important to have a thorough evaluation by a urologist, a specialist in urinary and male reproductive health.

In the meantime, medications that reduce pain and inflammation, such as those containing diclofenac sodium and serratiopeptidase, may be prescribed by your doctor to help manage symptoms. However, these should only be taken under medical supervision.

Recommendations:

• Seek prompt evaluation by a urologist to determine the exact cause of your pain.
• Avoid heavy lifting or strenuous activity until you have been assessed.
• If you experience sudden, severe pain, swelling, fever, or nausea, seek emergency medical care immediately.
