I'm sorry to hear about the itching and swelling you're experiencing. Itching around the groin and swelling of the testes can be caused by infections, inflammation, or other conditions that need careful evaluation.

You mentioned using Surfaz SN cream, which contains clotrimazole (an antifungal), neomycin (an antibiotic), and beclomethasone dipropionate (a corticosteroid). This cream is intended for fungal and bacterial skin infections and inflammation. However, since you have swelling of the testes along with itching, this could indicate a more serious issue such as an infection inside the scrotum or testicular inflammation, which requires prompt medical attention.

What you should do:

• Stop using the cream on the swollen area until a doctor evaluates you, as corticosteroids can sometimes worsen infections if not used properly.
• See a urologist (a specialist in urinary and male reproductive health) as soon as possible for a thorough examination.
• The doctor may perform physical examination, ultrasound, or lab tests to determine the cause of swelling and itching.
• Based on diagnosis, treatment may include antibiotics, antifungals, or other medications.
• Avoid tight clothing and keep the area clean and dry.
• Avoid any self-medication beyond what the doctor prescribes.

If you experience severe pain, fever, nausea, or worsening swelling, seek emergency care immediately.
