How is perianal pruritus treated?

Patient's question:

My rectal area is itchy to an extreme degree, I'm almost in pain, but I feel awkward scratching when going out, so I have to endure it. I consulted my doctor friend, and my friend said this condition is called Pruritus Ani. I thought the name was quite fitting. How is Pruritus Ani treated?

Doctor's answer:

1. Conservative treatment: Includes topical medication and injection therapy. Injection therapy is currently a commonly used method, characterized by simple operation and definite efficacy. This method involves injecting long-acting hormones into subcutaneous or dermal tissues to destroy sensory nerves, increase local sensation, and gradually eliminate symptoms.
2. Surgical treatment: The main objective is to sever subcutaneous nerve endings around the anus, making it suitable for intractable anal itching that does not respond to conservative treatment.
