Why Sitting Too Long Can Lead to Serious Leg Sores

It’s Just Sitting… So What’s the Big Deal?

You might think sitting is harmless—after all, it’s not like you’re running a marathon. But here’s the truth:

Sitting too long in one spot can cause painful leg sores.
And if left untreated, those sores can turn serious very quickly.

At American Surgeons Group, we see this often—especially in older adults, people with limited mobility, or those recovering from surgery.

Let’s break down why it happens, who’s at risk, and most importantly—how to prevent it.

What Are Leg Sores from Sitting?

They’re called pressure sores or pressure ulcers. You may have also heard them called bedsores—but they can happen while sitting, too.

When you sit too long in one position, the weight of your body cuts off blood flow to the skin and tissues under your thighs, buttocks, or back of the legs.

Over time, the skin breaks down, leading to:

  • Painful red areas

  • Open sores

  • Skin that dies or turns black (in severe cases)

Why Are They So Dangerous?

Pressure sores don’t always look bad at first—maybe just a red spot or a small sore. But under the surface, damage is building.

Without enough blood flow:

  • The skin starts to die

  • Infection can set in

  • The wound can grow deep—down to muscle or bone

In people with diabetes or circulation issues, even a small sore can become infected fast.

Who’s Most at Risk?

These sores don’t affect everyone the same way. You’re more likely to develop them if you:

  • Sit for long hours without shifting or standing up

  • Use a wheelchair or have limited mobility

  • Are bedridden or recovering from surgery

  • Have diabetes, nerve damage, or poor circulation

  • Have had pressure sores in the past

Where Do Leg Sores Usually Show Up?

Common pressure spots from sitting include:

  • Backs of the thighs (where they touch the chair)

  • Buttocks and tailbone

  • Heels if your feet rest on the ground or footplate

  • Behind the knees if they’re bent for too long

How to Know If a Pressure Sore Is Forming

Watch for early warning signs:

  • Skin that’s red, purple, or darker than normal

  • Area feels warm, painful, or itchy

  • The skin stays red even after pressure is relieved

  • You notice a blister or open sore

How to Prevent Pressure Sores from Sitting

The good news? Most pressure sores can be prevented with a few simple changes:

Change Positions Often

Shift your weight or stand up (if able) at least every 30–60 minutes. If you use a wheelchair, try a “push-up” movement or side-to-side shift.

Use Pressure-Relieving Cushions

Special foam or gel cushions can reduce pressure on your legs and backside. Ask your podiatrist which type is right for you.

Check Your Skin Daily

Look at your legs, buttocks, and heels every day—especially if you can’t feel them well. Use a mirror or ask someone to help.

Keep Skin Clean and Moisturized

Dry skin breaks down faster. Clean gently and moisturize regularly—but avoid lotion between toes or skin folds.

Stay Active

Even light stretching, leg lifts, or seated exercises help improve blood flow and reduce pressure buildup.

How a Podiatrist Can Help
