Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Brief answer: Examination or lab tests are needed to diagnose.
Detailed answer: There are a lot of reasons that can cause swelling of the testicles.
One of the most serious condition is
testicular torsion. In this case, the testicles twist inside the scrotum. This is considered a medical emergency because it causes a blockage of the blood flow to the testicles, which can lead to tissues damage or death. A
scrotal hernia may cause the swelling or a presence of a mass too.
In all these cases, it is necessary to perform an
ultrasound to be able to make the right diagnosis. Besides the reasons mentioned above, infections can cause the swelling of the testicles like
orchitis or
epididymitis.
So it is recommended to perform some lab tests, to determine the cause of the infection. If there is presence of infection, it is necessary to take a course of antibiotics. And after finishing the treatment, he should redo the lab tests to check if the treatment was effective or not.
Hope I have answered your query. Let me know if I can assist you further.

Dr. Genti Mulla
