I'm sorry to hear that you've been experiencing itching in your lower back and backside for two months. Persistent itching can be uncomfortable and may have various causes such as dry skin, allergic reactions, infections, or other skin conditions.

Here are some steps you can take:

• Keep the area clean and dry: Gently wash with mild soap and water, and pat dry.
• Avoid scratching: Scratching can worsen irritation and may lead to infection.
• Use moisturizers: Applying a gentle, fragrance-free moisturizer can help if dryness is a factor.
• Wear loose, breathable clothing: This helps reduce irritation and sweating.
• Avoid potential irritants: Such as harsh soaps, detergents, or tight clothing.

Since the itching has lasted for two months, it is important to consult a dermatologist (skin specialist) to determine the exact cause and receive appropriate treatment. They may recommend medications such as antihistamines or topical creams if an allergic or inflammatory condition is diagnosed.

One medication sometimes used for itching related to allergies is Avil (Pheniramine maleate), but this should only be taken under a doctor's prescription and guidance.

If you notice any additional symptoms like redness, swelling, pain, or signs of infection, please seek medical attention promptly.

Please consult a dermatologist for a thorough evaluation and personalized treatment plan.
