Finding raised bumps near your knees can be worrying, especially if your doctor’s appointment is still days or weeks away. The good news is that many skin bumps are harmless and often improve with simple home care. However, some can be a sign of an infection or another medical condition that needs prompt treatment.
While it’s impossible to diagnose skin conditions without an examination, understanding the most common causes can help you know what to watch for and when to seek medical attention.
Common Causes of Raised Bumps Around the Knees
Several conditions can cause small or large bumps to appear around the knees.
1. Folliculitis
Folliculitis occurs when hair follicles become inflamed, usually due to bacteria, yeast, or friction.
Symptoms may include:
- Small red bumps
- White or yellow pus-filled spots
- Mild pain or tenderness
- Itching
It often develops after shaving, sweating, or wearing tight clothing.
2. Keratosis Pilaris
Often called “chicken skin,” keratosis pilaris is a very common and harmless skin condition.
It happens when keratin builds up and blocks hair follicles.
Typical signs include:
- Tiny rough bumps
- Flesh-colored, white, or red spots
- Dry skin
- Usually no pain
It frequently appears on the thighs, upper arms, buttocks, and around the knees.
