Hello and welcome to HCM.
Thank you for your query.
1. Yes sir, this could be orchitis
, but it can only be confirmed after an examination by a doctor.
2. Treatment includes:
-Antibiotics (only if it is caused by an infection)
-Elevation of the scrotum
-Ice pack to the affected area
3. Orchitis is associated with congenital renal and urinary problems (among others)
