Hard lumps in the armpit: furuncles and carbuncles?


Previously, I had a hard lump under my armpit that resembled a pimple and would drain pus.
After it did not resolve after half a month, I went to see a doctor.
The doctor said it was nothing serious, and the diagnosis on the prescription was "furuncle and carbuncle." I was given medication and an ointment.
However, nearly a month has passed, and while the lump has shrunk, it has not completely disappeared.
It usually does not hurt when touched, but occasionally it does cause pain.
I would like to know if a furuncle or carbuncle can resolve on its own, or will it remain there indefinitely? Additionally, after finishing the medication prescribed by the doctor, I started feeling dizzy the next day.
I initially thought it was a personal health issue (I had experienced dizziness upon waking up in the past, but it resolved and I became more prone to dizziness afterward).
However, after finishing the medication on the third day, the dizziness went away.
Could this be due to an allergy or the medication being too strong? Should I inform the doctor about this when I go for a follow-up appointment? Thank you for your clarification.

Both of your questions should be discussed with your clinician.
I cannot address your concerns without seeing your lesions.

Understanding abscesses and boils is essential for effective management and treatment. An abscess is a localized collection of pus that can occur in any part of the body, often resulting from an infection. Boils, or furuncles, are a specific type of abscess that typically form in hair follicles and are characterized by a painful, swollen lump filled with pus. Both conditions can be caused by bacteria, most commonly Staphylococcus aureus, and can occur due to factors such as blocked sweat glands, ingrown hairs, or skin injuries.


Causes
The primary cause of abscesses and boils is bacterial infection. When bacteria enter the skin through a cut, scratch, or hair follicle, they can multiply and cause an inflammatory response, leading to the formation of pus. Other contributing factors include:
- Poor hygiene: Not keeping the skin clean can increase the risk of infection.

- Chronic skin conditions: Conditions like acne or eczema can predispose individuals to develop boils.

- Weakened immune system: Individuals with compromised immune systems are more susceptible to infections.

- Diabetes: This condition can impair the body’s ability to fight infections.


Symptoms
Common symptoms of abscesses and boils include:
- A painful, swollen lump on the skin that may be red and warm to the touch.

- The presence of pus, which may drain from the boil or abscess.

- Fever or chills in cases of systemic infection.

- Occasionally, surrounding skin may become inflamed or tender.


Treatment
Treatment for abscesses and boils typically involves:
1. Warm compresses: Applying a warm compress can help promote drainage and relieve pain.

2. Incision and drainage: In some cases, a healthcare provider may need to make a small incision to drain the pus.

3. Antibiotics: If the infection is severe or recurrent, antibiotics may be prescribed to help clear the infection.

4. Topical treatments: Antibiotic ointments may be applied to the affected area to prevent further infection.


Self-Care and Management
For individuals with abscesses or boils, self-care measures can include:
- Keeping the area clean and covered.

- Avoiding squeezing or popping the boil, as this can spread the infection.

- Monitoring for signs of worsening infection, such as increased redness, swelling, or fever.


Prognosis
Many abscesses and boils can resolve on their own, especially if they are small and not deeply rooted. However, larger or more persistent lumps may require medical intervention. It is not uncommon for a boil or abscess to take time to fully resolve, and in some cases, they may recur.


Regarding Your Symptoms
In your case, it seems that the hard lump under your arm has reduced in size but has not completely disappeared. This is not unusual, as some abscesses can take weeks or even months to fully resolve. If the lump continues to shrink and does not cause significant pain or discomfort, it may be on the path to healing. However, if it remains unchanged or begins to grow, it is advisable to follow up with your healthcare provider.

Regarding the dizziness you experienced after taking the medication, it is essential to inform your doctor during your next visit. Dizziness can be a side effect of certain medications, and it is crucial for your healthcare provider to know about any adverse reactions you experience. This information can help them adjust your treatment plan if necessary.

In summary, while abscesses and boils can often resolve on their own, monitoring their progress and maintaining communication with your healthcare provider is vital for ensuring proper treatment and management. If you have any concerns about the lump or your symptoms, do not hesitate to seek medical advice.
