Why does sudden testicular pain and swelling occur? What should be done?

Patient's question:

Testicular squeezing pain, tenderness, fullness pain, unable to bend over for the past three days

Doctor's answer:

Analysis of the condition: The main cause of this situation is likely to be varicocele. Additionally, it could be testitis or epididymitis. It is recommended to undergo an ultrasound examination for confirmation.
Advice: In general, if inflammation is confirmed, it is important to start intravenous fluid treatment as soon as possible. Local physical therapy can be combined. Avoid spicy and cold foods. During physical therapy, apply heat to the affected area. Wear loose underwear and avoid alcohol.
