Raised bumps near the knees are actually quite common, and in most cases they’re harmless, but sometimes they can indicate an underlying skin condition. Here’s a clear guide to help you understand what might be happening:
Common Causes of Raised Bumps on Knees
1️⃣ Keratosis Pilaris (“Chicken Skin”)
- Small, rough bumps, often skin-colored or slightly red
- Usually found on knees, upper arms, or thighs
- Caused by buildup of keratin blocking hair follicles
- Feels like sandpaper
Tips:
- Moisturize daily
- Gentle exfoliation with a loofah or chemical exfoliant (like lactic acid)
- Not harmful; cosmetic concern only
2️⃣ Eczema (Atopic Dermatitis)
- Red, itchy, inflamed bumps
- May ooze or crust if scratched
- Often worsens with dry skin, allergens, or irritants
Tips:
- Use fragrance-free moisturizers
- Avoid hot water and harsh soaps
- Over-the-counter hydrocortisone cream may help
3️⃣ Folliculitis
- Small, red or white-tipped bumps around hair follicles
- Can be itchy or mildly tender
- Caused by bacterial or fungal infection
Tips:
- Keep area clean
- Avoid tight clothing that rubs
- Topical antiseptics or antibiotics may be needed for persistent cases
4️⃣ Psoriasis
- Raised, red or pink bumps covered with silvery scales
- Often symmetrical and chronic
- Commonly affects knees, elbows, and scalp
Tips:
- Moisturize frequently
- Topical steroid creams may be prescribed
- Chronic condition; see a dermatologist for long-term management
5️⃣ Other Causes
- Allergic reactions to fabrics or soaps
- Insect bites
- Benign cysts or lipomas (rare)
When to See a Doctor
Seek medical advice if:
- Bumps are painful, spreading, or filled with pus
- There is persistent redness, swelling, or warmth
- You develop fever or other systemic symptoms
- Over-the-counter care doesn’t help
✅ Bottom Line
- Most raised bumps near the knees are harmless or manageable with home care
- Keratosis pilaris is the most common cause for teens and young adults
- Persistent, painful, or spreading bumps deserve a dermatologist check
