While lipomas are generally soft, movable, and often painless, they can sometimes cause discomfort or pain when pressed.
Most lipomas are benign fatty tumors that grow slowly and are typically found just under the skin. They are usually soft to the touch and can be easily moved with slight pressure. For many individuals, these growths remain asymptomatic, meaning they do not cause any pain or discomfort.
When a Lipoma Might Be Painful
Although commonly painless, a lipoma can become tender or painful when pressed under specific circumstances:
- Pressure on Nerves: If a lipoma grows to a considerable size, it may exert pressure on nearby nerves. This compression can lead to localized pain or discomfort, which often intensifies when the area is touched or pressed.
- Increased Vascularity: Some types of lipomas, known as angiolipomas, contain a higher concentration of blood vessels. These types of lipomas can be more sensitive and may cause pain or tenderness even without significant pressure on nerves.
- Location: The location of the lipoma can also influence whether it causes pain. Lipomas situated near joints, in areas prone to frequent friction, or deep within tissues might be more likely to cause discomfort when pressure is applied.
- Growth in Size: While many lipomas are relatively small, often less than 2 inches (5 centimeters) in diameter, they can continue to grow larger over time. A larger mass is more likely to impinge upon surrounding anatomical structures, leading to symptoms like pain upon pressure.
Understanding Lipoma Characteristics
To better understand when a lipoma might hurt, consider the following comparison:
| Characteristic | Typical Lipoma (Usually Painless) | Painful Lipoma Scenarios |
|---|---|---|
| Feel | Soft, doughy, or rubbery; easily movable under the skin | Tender or firm; pain increases when pressed |
| Size | Commonly small, often under 2 inches (5 cm) in diameter | Can grow larger, potentially exceeding 2 inches (5 cm) |
| Mobility | Freely movable under the skin | May feel less mobile if adhered to deeper structures or pressing nerves |
| Cause of Pain | Generally none | Pressure on nerves, presence of many blood vessels (angiolipoma) |
What to Do If a Lipoma Is Painful
If a lipoma causes persistent pain, tenderness, grows rapidly, or undergoes any other noticeable changes, it is advisable to consult a healthcare professional. While most lipomas are benign, a medical evaluation can help confirm the diagnosis and rule out other potential conditions. Treatment for painful lipomas often involves surgical removal to alleviate symptoms and ensure an accurate diagnosis.
