Itching, swelling, and a bad odor on the scrotum - what should I do?

Patient's question:

Patient Gender: Male
Scrotal surface itching, swelling, and a small blister inside the foreskin. Additionally, there is a foul odor.

Doctor's answer:

Medication can be effective to a certain extent, such as taking antihistamines under the guidance of a doctor or applying topical medium- and low-potency corticosteroid creams. Although corticosteroid creams have a definite therapeutic effect, their use should not be prolonged or excessive in dosage. Additionally, sometimes, under the guidance of a doctor, some traditional Chinese medicine therapies or physical therapies can also yield certain effects.
