Underarm Bumps: Causes, Symptoms, and Treatment Options - Surgery

More Info

---

Understanding underarm bumps can be concerning, especially when they resemble larger pimples or cysts. Based on your description, it sounds like you may be dealing with a condition known as an epidermoid cyst or possibly an abscess. Let’s break down the potential causes, symptoms, and treatment options for these types of bumps.


Causes
1. Epidermoid Cysts: These are benign (non-cancerous) lumps that form when skin cells multiply and become trapped beneath the skin. They are often filled with keratin, a protein found in skin, hair, and nails. These cysts can occur anywhere on the body, including the underarm area.

2. Abscesses: An abscess is a collection of pus that forms due to an infection. It can occur when bacteria enter the skin through a cut or hair follicle, leading to inflammation and pus formation. Abscesses can be painful and may require medical intervention.

3. Folliculitis: This is an inflammation of the hair follicles, often caused by bacterial or fungal infections. It can lead to red, swollen bumps that may resemble pimples.

4. Hidradenitis Suppurativa: This is a chronic skin condition characterized by lumps under the skin, often in areas where skin rubs together, such as the armpits. It can cause painful abscesses and scarring.


Symptoms
- Size and Appearance: The bump you described as being larger than a pimple and recurring suggests it could be a cyst or abscess.

- Discharge: The presence of white fluid and blood when it bursts is indicative of an infection or cyst.

- Pain or Discomfort: If the bump is painful or tender to the touch, it may be an abscess or an inflamed cyst.

- Recurrent Nature: The fact that it keeps coming back in the same spot suggests a chronic issue, possibly related to blocked glands or hair follicles.


Treatment Options
1. Observation: If the bump is not causing pain or discomfort, and if it is not growing, your doctor may recommend simply monitoring it.

2. Warm Compresses: Applying a warm compress can help reduce inflammation and promote drainage if it is an abscess.

3. Incision and Drainage: If the bump is painful or has become an abscess, a healthcare provider may need to perform a minor procedure to drain the pus and relieve pressure.

4. Surgical Removal: For recurrent cysts or those that cause significant discomfort, surgical removal may be necessary. This procedure involves excising the cyst and its contents to prevent recurrence.

5. Antibiotics: If there is an infection present, your doctor may prescribe antibiotics to help clear it up.

6. Lifestyle Modifications: Keeping the area clean and avoiding tight clothing can help prevent irritation and recurrence.


Conclusion
It is essential to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan. They can perform a physical examination and may recommend imaging studies if necessary. If the bump is indeed an epidermoid cyst or an abscess, they can provide you with the best options for management, including potential surgical intervention if required. Remember, while many skin bumps are benign, it’s always best to err on the side of caution and seek medical advice, especially if there are changes in size, color, or associated symptoms like pain or fever.
