Medical consultation: Persistent black pus?
I have developed something that resembles a pimple below my waist due to frequent walking during my commute.
I'm not sure what it is.
It is black, feels like there is pus inside, and the surrounding area has scabbed over.
I have tried to squeeze it with my hands, but it doesn't come out like a regular pimple.
It has been on my body for six months (what could it be?).
What ointment should I apply, or should I use a needle...?

More Info
Persistent black bumps on the skin can be concerning, especially when they resemble acne but do not respond to typical treatments. Based on your description, it sounds like you may be dealing with a type of cyst, possibly a sebaceous cyst or an epidermoid cyst. These cysts can appear as firm, round lumps beneath the skin and may sometimes become inflamed or infected, leading to pain, redness, and the formation of pus.
Understanding Sebaceous and Epidermoid Cysts
Sebaceous cysts, also known as epidermoid cysts, are common skin conditions that occur when a hair follicle or skin pore becomes blocked. This blockage can lead to the accumulation of sebum (an oily substance produced by sebaceous glands) and dead skin cells, forming a cyst. These cysts can vary in size and may be skin-colored, white, or black, depending on their contents and the degree of inflammation.
Symptoms and Diagnosis
The symptoms you describe—persistent black bumps that feel like they have pus inside and are surrounded by scabbing—suggest that there may be some inflammation or infection present. The fact that these bumps have been present for six months without improvement is also noteworthy. Typically, sebaceous cysts are not painful unless they become infected. When infected, they can become red, swollen, and tender to the touch.
To accurately diagnose the condition, a healthcare professional would typically perform a physical examination. In some cases, imaging studies like an ultrasound may be used to assess the cyst's characteristics. If there is any suspicion of a more serious condition, a biopsy may be recommended.
Treatment Options
1. Observation: If the cyst is not causing pain or discomfort, a "watchful waiting" approach may be taken. Many cysts can resolve on their own over time.
2. Medications: If there is inflammation or infection, your doctor may prescribe antibiotics to treat the infection. Topical treatments, such as benzoyl peroxide or salicylic acid, may help if the bumps are acne-related.
3. Drainage: If the cyst becomes painful or infected, a healthcare provider may perform a procedure to drain the cyst. This is typically done in a sterile environment to prevent further infection.
4. Surgical Removal: If the cyst is recurrent or bothersome, surgical removal may be the best option. This procedure is usually performed under local anesthesia and involves excising the cyst along with its sac to prevent recurrence.
Home Remedies and Caution
While it may be tempting to try to pop or drain the cyst at home, this is generally not recommended. Attempting to squeeze or puncture the cyst can lead to further inflammation, infection, and scarring. Instead, keep the area clean and avoid irritating it. Over-the-counter topical treatments may help, but it's essential to consult a healthcare provider for the best course of action.
When to Seek Medical Attention
You should seek medical attention if:
- The bumps become increasingly painful or swollen.
- You notice any discharge that is foul-smelling or has a significant change in color.
- The bumps continue to grow or change in appearance.
- You develop fever or other systemic symptoms.
In conclusion, while persistent black bumps can be concerning, they are often manageable with appropriate medical care. Consulting a dermatologist is the best way to determine the exact nature of your condition and receive tailored treatment options.
