What is the reason for a dull ache at the upper part of the base of the penis (scrotum)?

Patient's question:

Detailed medical history and purpose of consultation: None
Current general condition: None
Medical history: None
Auxiliary tests: None
　　Previously, I had experienced mild, dull pain in the upper part of the base of the penis (scrotum). Recently, I noticed a round lump above the epididymis, which causes radiating pain when touched, i.e., dull pain. Is this lump a sign of anything serious?

Doctor's answer:

Hello, orchitis, testicular cysts, hydrocele, epididymitis, varicocele, prostatitis, etc., can all cause dull pain in the lower part of the base of the penis and above the testicles. This requires further examination to determine the cause. You can go to a local hospital, the urology department, find a doctor to perform a physical examination, check which specific area is problematic, and conduct the corresponding tests to confirm the diagnosis.
