What are the early symptoms of orchitis?

Patient's question:

Left testicular swelling, examination said there is inflammation, currently there is aching pain near the genital area, can't do anything, please ask what are the early symptoms of orchitis

Doctor's answer:

Okay, here is the translation following your instructions:
I. The body produces high fever symptoms and also experiences chills.
II. Pain in the testicles, accompanied by pain in the scrotum, groin area, and most of the inguinal region.
III. The testicles become red, swollen, and enlarged, with tenderness; a slight touch elicits a sense of internal fluid accumulation.
IV. Often accompanied by redness and swelling of the scrotal skin and the recurrence of fluid accumulation within the tunica vaginalis.
Testicular inflammation tends to be recurrent, requiring long-term medication for management. Moreover, for male patients, it is important to seek diagnosis at professional and reputable hospitals promptly, and treatment should be considered based on the results of a thorough examination.
