It's likely that the "little white ball" you're feeling in your armpit is a lump which could be caused by several different things. According to the provided reference, these can include swollen lymph nodes, infections, or cysts.
Understanding Armpit Lumps
Lumps in the armpit can vary in size, feel, and cause. Here's a breakdown of the common possibilities:
Swollen Lymph Nodes
- What they are: Lymph nodes are small, bean-shaped organs that are part of your lymphatic system, which filters fluid around your cells. They are a crucial part of your immune system.
- Why they swell: When your body is fighting an infection, the lymph nodes in that area may swell as they work to eliminate the harmful substances. This can make them feel like a small, tender lump.
- How they might feel: These lumps may be tender to the touch and sometimes accompanied by other symptoms like fever or fatigue.
Infections
- How they cause lumps: Infections, either local to the armpit area or systemic, can cause inflammation and swelling, resulting in a lump. This can be due to bacteria, viruses, or even fungal infections.
- Types of infection: Boils or abscesses in the armpit can present as a lump and can cause pain and redness.
Cysts
- What they are: Cysts are fluid-filled sacs that can develop under the skin. They're generally harmless.
- Why they form: Cysts can occur for various reasons, including blocked hair follicles or oil glands.
- How they feel: They may feel like a smooth, movable lump beneath the skin.
What to Do
While the information above offers general explanations, it's important to:
- Monitor: Keep an eye on the lump for any changes in size, shape, color, or tenderness.
- Consult a doctor: If the lump persists, grows, is painful, or is accompanied by other symptoms (like fever or redness), consult a healthcare professional for an accurate diagnosis and appropriate treatment.
| Possible Cause | Description |
|---|---|
| Swollen Lymph Node | Small, bean-shaped organ that swells in response to infection |
| Infection | Can lead to inflammation and lump formation due to bacteria or viruses |
| Cyst | Fluid-filled sac under the skin, usually harmless |
