Calluses are thickened areas of hard skin that usually form because of repeated pressure or friction. They are common on the feet, especially under the ball of the foot, around the heel, or near the big toe.
A callus is not always painful. In fact, hard skin often develops as your body’s way of protecting the area. But when a callus on your foot hurts, it usually means there is too much pressure building in one spot.
If your pain is not coming from hard skin, or your whole foot hurts and you are not sure why, our wider guide to foot pain, causes and symptoms may be more useful. But if you know full well the problem is painful calluses, keep reading…
Why Do Calluses On Feet Hurt?
Painful calluses on feet usually happen when thickened skin presses into the softer tissue underneath. This can feel like walking on a small stone, especially if the hard skin is under the ball of the foot or beneath a toe joint.
A painful callus on the foot can be caused by:
- pressure from tight or unsupportive shoes
- high-pressure areas under the foot
- changes in the way you walk
- prominent joints or bony areas
- long periods standing or walking
- reduced natural cushioning under the foot
If hard skin under your foot is painful when walking, the problem is often not just the skin itself. The callus is usually a sign that pressure is not being spread evenly through the foot. We cover walking-related causes separately in our guide to foot pain when walking.
Hard Skin, Corn, Verruca Or Something Else?
Hard skin can be confusing because several foot problems can feel similar.
A callus is usually a broader patch of thickened skin. A corn is smaller and more concentrated, often with a painful central point. A verruca may have tiny black dots, a rougher surface and can hurt when squeezed from the sides. Pain under the ball of the foot without obvious hard skin may be linked to pressure overload, joint irritation or a neuroma.
Location can help. Hard skin on the heel may cause surface pain or cracking, while deeper heel pain may need to be assessed differently. Our sore heel guide explains heel-specific causes. If the pain sits through the inner arch rather than under an area of hard skin, our guide to arch pain and fallen arches may be more relevant.
Burning, tingling, numbness or night pain should not be treated as simple callus pain. Those symptoms can suggest nerve involvement and may need a different assessment. See our guides to burning feet at night and diabetic foot pain for more on those symptoms.
What Can You Do Safely At Home?
You can help reduce painful hard skin by wearing comfortable, well-fitting shoes and avoiding footwear that rubs or squeezes the toes. Moisturising your feet can help keep hard skin softer, and gentle filing may help some people.
However, you should not cut calluses off yourself. Blades, scissors and aggressive filing can damage healthy skin, cause bleeding or create a wound. This is especially important if you have diabetes, poor circulation, reduced sensation, or a history of foot ulcers.
If you want more general home-care advice, read our guide to callus removal at home. If you are tempted to cut hard skin, corns or calluses yourself, read why you should never DIY corn and callus removal first.
When Should You See A Podiatrist?
Book an appointment if a callus on your foot hurts, keeps coming back, affects walking, or feels like a hard lump under the skin. You should also seek advice if the area is cracked, bleeding, red, swollen, warm, or changing shape.
A podiatrist can remove painful hard skin safely, check why the pressure is building, and advise on padding, footwear, insoles or ongoing care to reduce the chance of it coming back.
At Northwich Foot Clinic, we can assess painful calluses, corns and hard skin, relieve discomfort and help you understand what is causing the pressure in the first place.
