Testicular pain and a twisting sensation over several months may be caused by conditions such as testicular torsion (the cord supplying blood to the testicle twists), varicocele (enlarged veins in the scrotum), infection, or a hernia (abdominal tissue pushes into the scrotum). You should consult your doctor promptly, preferably a urologist, to determine the exact cause and receive appropriate treatment. Avoid delaying, as prolonged twisting can affect testicular function. Do not try to manipulate the testicle yourself, and seek medical care as soon as possible to prevent complications.
