Not All Ulcers Are the Same — Here’s Why That Matters

If you’ve noticed a sore on your lower leg or foot that just won’t heal, you might be wondering:
“Is this a leg ulcer or a foot ulcer?” And does it even matter?

The short answer is — yes, it matters a lot.

Even though they can look similar on the surface, leg ulcers and foot ulcers often have very different causes, risks, and treatment needs. Understanding the difference can help you take the right steps toward healing and avoid serious complications.

Let’s break it down.

What Is an Ulcer, Exactly?

An ulcer is an open sore or wound that takes a long time to heal — or doesn’t heal at all. Ulcers happen when the skin breaks down and deeper tissue becomes exposed. They’re usually caused by poor circulation, nerve damage, pressure, or a combination of these.

Ulcers are more common in people with diabetes, vein disease, or limited mobility.

Foot Ulcers: What to Know

Foot ulcers are open sores that develop on the bottom of the foot, the toes, or around the heel.

Causes:

  • Diabetic neuropathy (nerve damage that prevents you from feeling pain)

  • Poor circulation (often from diabetes or PAD)

  • Pressure and friction from walking, tight shoes, or foot deformities

  • Injury you didn’t notice or treat

What They Look Like:

  • A crater-like sore or open wound

  • Often surrounded by callused or dry skin

  • May be painless (especially if you have nerve damage)

  • Can become infected quickly if untreated

Risks:

  • Infection that spreads to the bone

  • Tissue death (gangrene)

  • In severe cases, amputation

Leg Ulcers: What to Know

Leg ulcers usually appear on the lower leg, especially around the shin or ankle area.

Causes:

  • Venous insufficiency (poor blood flow in the veins)

  • Varicose veins

  • Swelling in the legs that doesn’t go down

  • Sometimes caused by arterial disease or inflammation

What They Look Like:

  • A shallow, slow-healing sore

  • Skin around the ulcer may look brownish, reddish, or shiny

  • May ooze fluid or feel itchy

  • Often surrounded by swollen, irritated skin

Risks:

  • Ongoing discomfort and swelling

  • Repeated infections

  • Risk of ulcers coming back if circulation issues aren’t treated

Why Podiatrists Treat Both

You might think podiatrists only treat the foot—but at American Surgeons Group, we also treat wounds on the lower leg, especially when they’re connected to foot or circulation problems.

Our team looks at the whole picture—blood flow, nerve function, skin health, pressure points, and more. Whether it’s a foot ulcer from diabetes or a venous leg ulcer from circulation issues, we’re trained to manage it from start to finish.

How We Help You Heal

When you come in with a sore on your leg or foot, here’s what we might do:

  • Examine the ulcer carefully to identify the type and depth

  • Check blood flow and nerve function

  • Debride (clean out) the wound safely

  • Apply advanced dressings that promote healing

  • Relieve pressure with orthotics, boots, or pads

  • Coordinate care if a vascular specialist or other provider is needed

  • Create a plan to protect the area and prevent new ulcers

Home Care and Prevention Tips

Even after an ulcer starts healing, it’s important to protect your skin and circulation:

  • Check your feet and legs daily for new spots or color changes

  • Moisturize dry skin, but don’t overdo it between toes

  • Avoid walking barefoot

  • Wear compression socks (if recommended)

  • Manage blood sugar levels and stay active to improve circulation

  • Keep legs elevated if swelling is a problem

When to Seek Help

Here’s the bottom line: Don’t ignore a sore that isn’t healing.
If you see redness, swelling, drainage, or the wound gets worse—or if you have diabetes—get it checked out as soon as possible.
