Sudden cramp-like pain in the testicles is generally considered to be related to orchitis, and also to epididymitis. This situation may be related to the following reasons, such as cold stimulation, poor immunity, frequent late nights, overwork, etc. It is advisable to go to the hospital in time for relevant examination and treatment. You can do scrotal ultrasound examination to determine whether the male has epididymitis or orchitis, and also to rule out the possibility of testicular torsion. The most serious consequence of testicular torsion is that it can lead to testicular necrosis, so it must be taken seriously.
