The short version
At a glance
- Corns tend to be small and focused; calluses usually cover a broader area.
- Reducing rubbing and pressure matters—not just removing thick skin.
- Do not cut corns or calluses yourself.
- If you have diabetes or poor circulation, get advice before attempting treatment.
- Bleeding, discharge or severe pain needs medical assessment.
General information, not individual medical advice.
Small pressure point or wider patch?
A corn is typically a small, deeper area of hardened skin with a central core. It may hurt when pressed. Hard corns often appear on toes; softer corns can develop between them. A callus is usually a broader patch over a weight-bearing area, such as the heel or ball of the foot.
Both can develop where skin repeatedly rubs or bears pressure. Tight shoes can squeeze; loose shoes can allow sliding. Foot shape can also affect where pressure lands. These descriptions are not enough to identify your own skin problem with certainty.

Start with the pressure—not a blade
Choose supportive footwear that does not rub, with room for your toes, and comfortable cushioned socks. If a spot keeps returning, ask a qualified foot-care professional to assess the pressure and whether treatment or a footwear change is appropriate.
Do not slice, shave or dig at thick skin yourself. If you have diabetes, poor circulation or a weakened immune system, seek professional advice instead of trying home removal.

If you have diabetes
Diabetes Canada advises against cutting your own corns or calluses and against over-the-counter corn or wart medicines. Check your feet daily, using a mirror or help if needed. Wash and dry them carefully; do not soak them. Moisturizer can be used on heels and soles, but not between the toes.
New warmth, redness, swelling or pain needs prompt attention from your doctor or foot specialist. Do not wait for a routine booking to be confirmed.

When routine care is not enough
Arrange medical assessment if the area bleeds, has discharge, or is severely painful or interfering with normal activities. A suspected infection or open wound should not be treated as a straightforward corn-removal appointment.
