Bacterial infection


Hello doctor, two weeks ago I developed a lump on my buttocks.
I went to the emergency room that evening, and the doctor mentioned it might be a bacterial infection.
He seemed to refer to it as a carbuncle (I'm not sure if he said it in English or Mandarin) and prescribed painkillers, stomach medication, and antibiotics.
He advised me to see a surgeon afterward (I'm not sure if I should see a surgeon or a dermatologist).
Later, it started to drain pus.
It no longer hurts, so I didn't pay much attention to it.
However, this week, a similar lump appeared next to my knee.
I went to a nearby clinic to see a dermatologist, and he also said it was a bacterial infection and that I could only take medication.
He advised that if pus comes out, I should disinfect it with iodine.
But it seems like the pus is not draining completely.
I feel like what’s coming out looks like blood and fat.
It might be because it's located in a weight-bearing area like the knee.
Is that correct? I’m feeling quite anxious about it.
Should I go to a larger hospital? However, he mentioned that if it doesn't persist, the bacteria could develop resistance to the medication.
So I'm unsure what to do.
Actually, it doesn't hurt (after the lump burst).
I don't know what to do.
I'm still taking the medication, but I'm not applying anything externally.
Could you please give me some advice? Thank you.

Hello: The carbuncle mentioned by that doctor is actually referred to as "carbuncle" in English.
It is a type of bacterial folliculitis that occurs at a deeper and more severe level.
If it gradually decreases in size after medication, surgical incision and drainage may not be necessary.
However, if it remains very painful and does not improve, incision and drainage may be required.
If the same issue recurs, it could indicate incomplete treatment, so it is best to consult a dermatologist.

More Info


It sounds like you are experiencing a challenging situation with recurrent skin infections that may be bacterial in nature. Based on your description, it appears that you have developed abscess-like lesions that have caused you concern, especially with the presence of pus and the potential for complications. Here’s a comprehensive overview of bacterial skin infections, their treatment options, and what steps you might consider taking next.


Understanding Bacterial Skin Infections
Bacterial skin infections can manifest in various forms, including abscesses, cellulitis, and folliculitis. The abscess you mentioned, which is a collection of pus that can occur due to bacterial infection, often presents as a painful, swollen lump. The presence of pus indicates that the body is fighting an infection, and it may contain bacteria, dead cells, and other debris.


Common Bacterial Pathogens
The most common bacteria responsible for skin infections include Staphylococcus aureus and Streptococcus pyogenes. In some cases, more resistant strains like Methicillin-resistant Staphylococcus aureus (MRSA) can also be involved, particularly if the infection is recurrent or not responding to standard antibiotics.


Treatment Options
1. Antibiotics: The first line of treatment for bacterial skin infections typically involves antibiotics. Since you have already been prescribed antibiotics, it is crucial to complete the entire course as directed, even if the symptoms improve. This helps prevent the development of antibiotic resistance.

2. Drainage: If an abscess is present, it may need to be drained. This procedure is usually performed by a healthcare professional. Drainage can relieve pressure, reduce pain, and allow for better penetration of antibiotics into the infected area.

3. Topical Treatments: In some cases, topical antibiotics or antiseptics may be recommended to help manage the infection and promote healing. Using a product like Betadine (povidone-iodine) as you mentioned can help disinfect the area, but it should be used as directed.

4. Pain Management: Over-the-counter pain relievers can help manage discomfort associated with the infection.


When to Seek Further Medical Attention
Given that you have experienced recurrent infections and the presence of pus, it may be prudent to seek further evaluation from a specialist. Here are some signs that warrant immediate medical attention:
- Increased redness or swelling: If the area around the infection becomes more inflamed, it may indicate that the infection is worsening.

- Fever: A fever can be a sign that the infection is systemic and requires more aggressive treatment.

- Persistent or worsening symptoms: If the pus continues to drain or if you notice blood or fatty tissue, it may be necessary to have the area examined to rule out complications.

- Recurrent infections: If you find that you are experiencing repeated infections, it may be beneficial to consult with a dermatologist or an infectious disease specialist.


Conclusion
In summary, while it is essential to follow your current treatment plan, you should remain vigilant for any signs of worsening infection. If your symptoms do not improve or if you have concerns about the nature of the drainage, seeking care from a larger medical facility or a specialist may provide you with the answers and treatment you need. Remember, early intervention can prevent complications and promote better healing outcomes. Always prioritize your health and do not hesitate to seek help when needed.
