Itchy red bumps on the buttocks can be caused by a variety of factors, and understanding the underlying reasons is essential for effective treatment. Based on your description, it seems that you initially had a couple of bumps that have since multiplied, which suggests a possible infectious or inflammatory process. Here are some common causes of itchy red bumps in that area:
1. Folliculitis: This is an inflammation of the hair follicles, often caused by bacterial infection (most commonly Staphylococcus aureus) or fungal infection. It can result in red, itchy bumps that may resemble acne. Folliculitis can occur due to friction from clothing, sweating, or shaving.

2. Contact Dermatitis: This condition occurs when the skin reacts to a substance it has come into contact with, such as soaps, detergents, or certain fabrics. If you have recently changed laundry detergents or used new personal care products, this could be a potential cause.

3. Heat Rash: Also known as prickly heat, this condition occurs when sweat ducts become blocked, leading to small, itchy red bumps. It is more common in hot and humid conditions and can occur on the buttocks if you sweat excessively.

4. Psoriasis: This is a chronic autoimmune condition that can cause red, scaly patches on the skin. While it commonly affects the elbows and knees, it can also appear on the buttocks.

5. Eczema: Atopic dermatitis, or eczema, can cause itchy, red patches on various parts of the body, including the buttocks. It is often associated with dry skin and can be triggered by allergens or irritants.

6. Insect Bites: Bites from mosquitoes, fleas, or other insects can cause localized red, itchy bumps. If you have pets or have been in areas where insects are prevalent, this could be a possibility.

7. Scabies: This is a contagious skin condition caused by tiny mites that burrow into the skin, leading to intense itching and a rash. It often affects areas where skin folds, including the buttocks.

8. Fungal Infections: Conditions like tinea (ringworm) can cause red, itchy patches on the skin. These infections thrive in warm, moist areas, making the buttocks a potential site for infection.

Given that your condition has worsened, it is advisable to take the following steps:
- Avoid Scratching: Scratching can worsen the irritation and lead to secondary infections. Try to keep the area clean and dry.

- Topical Treatments: Over-the-counter hydrocortisone cream can help reduce inflammation and itching. Antihistamines may also provide relief from itching.

- Monitor Symptoms: Keep an eye on the bumps. If they continue to spread, become painful, or if you develop fever or other systemic symptoms, it is crucial to seek medical attention.

- Consult a Dermatologist: If the condition does not improve with home care or if you are uncertain about the cause, a dermatologist can provide a proper diagnosis and treatment plan. They may perform a skin scraping or biopsy to determine the exact cause of your symptoms.

In summary, itchy red bumps on the buttocks can arise from various causes, including infections, allergic reactions, and skin conditions. Identifying the underlying cause is key to effective treatment, so if symptoms persist or worsen, professional medical advice is recommended.
