Detailed Answer:
Hello,

Welcome and thanks for posting your query to the forum.

I can understand your concern for the problem of pain in the lower buttock region along with whitish yellow eruption.

after analyzing the picture with best diligence I can make out that you have Folliculitis or simply saying boil over the buttock region. As per the appearance it is evident that it has formed bit larger and is getting converted into a cyst.

To tell you simply - This is a condition of inflammation and infection of the hair root and oil gland attached to it which is medically known as folliculitis.

To explain it medically, we have hair all over our body which have opening of the oil glands attached to it. By many a factors these hair root and oil gland can become inflamed and infected leading to folliculitis.

The reason for the inflammation and infection of the area is due to the fact that our body harbor multiple types of bacteria on the skin which are known as “Normal flora” of the skin.

Most specifically the bacteria “Staphylococcus aureus” is also a part of that flora, but as soon as there is some break in the skin or trivially also due to bit ups and downs in immunity, the bacteria gets access into the skin and causes the aforesaid process of inflammation and infection.

Buttock area is bit moist and have high bacterial proliferation near anus therefore is more prone for such kind of infections.

When it is superficial it heals without any problem, but when it is deep it causes lot of pain and swelling around the area. This larger area with more pus collection is known as cyst. You can see int he picture that the area is bigger than a simple boil and there is redness around making it evident that the infection is bit deeper and has formed a cyst.

There are certain important tips regarding your problem:

1. Do not pinch, pop or even try to touch the area.

2. Kindly avoid scratching any area of normal skin also, as it leads to minor entry points for the entry of bacteria.

3. Maintain proper hygiene and take two times daily bath.

4. Wear cotton clothes and cotton undergarments.

5. Change the undergarments for two times in a day.


In your kind of condition a proper antibiotic therapy is very much required along with anti-inflammatory drugs.

In my patients I prefer to give higher antibiotic with Amoxycillin and clavulinic acid or cefixime with clavulinic acid in proper dose.

An anti-inflammatory tablet with paracetamol or ibuprofen or diclofenac for 2-3 times day is required to reduce the inflammation and pain.

I suggest you to meet your doctor again as it may turn into an abscess if not treated early with proper medications.

Hope above information will help you. If you have any further questions, I will be happy to help.
Wish you good health.
