Home remedies for treating an enlarged or swollen testicle include applying ice during the first 24 hours, soaking in a sitz bath, wearing athletic support and taking over-the-counter pain medications, states Healthline. If sudden, severe pain accompanies the swelling, the individual requires immediate medical care to prevent potential scrotal tissue death.
A number of conditions can cause testicular or scrotal swelling, many of which are serious and require medical treatment that varies according to the condition, advises Healthline. A swollen testicle may result from testicular cancer, enlarged scrotal veins, testicular inflammation, fluid accumulation and hernia. Treatments may involve antibiotics, anti-inflammatory medications, surgery, chemotherapy or radiation, depending on the cause of the swelling. A doctor may recommend home treatments, such as sitz baths and athletic supports, in addition to medical treatment.
Testicular torsion occurs when the testicle twists within the scrotum, cutting off the blood supply, explains Healthline. This causes painful swelling of the scrotum. Without appropriate medical treatment, the tissue within the scrotum can die within a matter of hours. Surgery is almost always necessary to treat testicular torsion, notes MedlinePlus. If a doctor performs surgery within six hours after symptoms begin, he can usually preserve the patient's testicle.
To diagnose the cause of an enlarged testicle, a doctor performs a physical examination and asks about the patient's activities at the time he noticed the swelling, says Healthline. He may also conduct an ultrasound to detect any abnormalities. He then prescribes medications and home treatments as necessary or recommends other interventions, such as surgery.
