I'm sorry to hear about the persistent anal itching and discomfort you've been experiencing. Chronic anal itching lasting over two years, especially with a sensation of hardness in the area, warrants a thorough evaluation to determine the underlying cause.

Possible causes include:

• Chronic irritation or inflammation
• Hemorrhoids or anal skin tags
• Fungal or parasitic infections
• Dermatitis or other skin conditions
• Other less common conditions such as anal fissures or growths

Recommended steps:

• Schedule an appointment with a colorectal surgeon or a gastroenterologist for a detailed physical examination.
• The doctor may perform an anoscopy (a small scope to look inside the anal canal) or other diagnostic tests to identify the cause.
• Avoid scratching the area to prevent further irritation or infection.
• Maintain good hygiene and keep the area dry.
• Over-the-counter topical treatments may provide temporary relief but should be used only after consulting a doctor.

Given the duration and symptoms, it is important to seek professional medical evaluation to receive an accurate diagnosis and appropriate treatment.

If symptoms worsen or you experience new signs such as bleeding, severe pain, or lumps, please seek urgent medical attention.
