The Diabetic Pedicure Request
A 63-year-old woman books a deluxe pedicure. During intake she mentions she has had type 2 diabetes for 14 years, her most recent A1C was 9.4%, and her doctor recently added a second medication. She reports tingling and numbness in both feet, worse at night, and says she "can't really feel" the water temperature when she tests it at home. On inspection, the skin on both lower legs is shiny and hairless below the knee, the toenails are thick and yellowed, and there is a 1 cm callus on the ball of the right foot with a small dark red spot inside it. Her right foot feels cooler than the left, and the pedal pulse on the right is difficult to find. She asks for the callus to be shaved off with a credo blade and wants the water "as hot as you can stand."
1. Which findings point to peripheral neuropathy and peripheral arterial disease, and why do they change how this service is performed?
Read the worked answer
Neuropathy indicators: the reported tingling and numbness, the burning at night, and - most importantly - her inability to judge water temperature at home. Loss of protective sensation means she cannot feel heat, pressure, or a nick, so she cannot warn the technician when something is too hot or too sharp, and she will not notice a small injury until it is far along.
Circulatory indicators: shiny, hairless skin below the knee, a right foot cooler than the left, and a difficult-to-find pedal pulse. These suggest reduced arterial blood flow. Tissue that is poorly perfused heals slowly and becomes infected easily, so any break in the skin is a serious event rather than a minor one.
The dark red spot inside the callus is the finding that should stop the technician cold. A callus is a pressure injury, and a red, purple, or black area beneath one can be a subcallus hemorrhage - often the first visible sign of an ulcer forming. It must not be filed, cut, or probed.
Together these findings mean the margin for error is close to zero. A burn, a cut, or an over-filed callus that would heal in days on another client could become an ulcer, an infection, or worse in this one. The A1C of 9.4% reinforces that her healing is currently impaired.
2. Which parts of the requested service must be declined, and why?
Read the worked answer
Decline, and explain why, all of the following:
- The credo blade. A credo is a sharp blade used to shave callus. Even in skilled hands it can remove living tissue and create a break in the skin, and many jurisdictions restrict or prohibit its use. On a neuropathic, poorly perfused foot, that break is a direct route to infection and a potential ulcer. The dark red spot makes it an absolute no - cutting into it could turn a warning sign into an open wound.
- Hot water. She cannot feel temperature, so she cannot tell the technician when the water is scalding. Water should be lukewarm, around 38 °C / 100 °F, checked with a thermometer, not with a hand alone, and the soak kept short.
- Aggressive filing or scraping of the callus. Reducing a callus on a high-pressure area without addressing the pressure often makes the body rebuild it thicker, and thinning it invites breakdown.
- Cuticle cutting and sharp nipping around the nails. Any nick is a wound. Push back gently, and do not cut living tissue.
- Vigorous massage of the lower leg in a client with poor circulation; pressure on a compromised limb is not worth the risk. Gentle foot massage of the dorsum with light pressure is acceptable if the skin is intact.
Saying "no" is the service here. Each refusal should be paired with what the salon can do instead, so the client does not simply go elsewhere and get the shave she asked for.
3. What can be safely provided today, what referral is needed, and what education should she leave with?

Safe today: a gentle, lukewarm soak with a thermometer check; cleansing with a mild soap; careful nail shaping with a file rather than clippers on the thick nails; gentle cleaning under the free edge; light moisturizing of the skin - avoiding the spaces between the toes, where trapped moisture feeds fungus; and a light foot massage only if the skin is intact and the client is comfortable.
Referral: the callus with the dark red spot and the cool, pulseless right foot need a podiatrist or physician before any further pedicure work on that foot. Say it plainly: "There's a spot under this callus that I'm not going to touch. It needs to be looked at by someone who can see the tissue underneath." Offer to write down what was observed and where. If she reports any new opening, redness, warmth, or odor, she should call her doctor promptly, not book another appointment.
Education to leave with: check both feet daily, including the soles, using a mirror or a family member; test bath water with a thermometer or elbow, never the feet; never walk barefoot, even indoors; wear well-fitting shoes and check them for objects before putting them on; do not self-treat calluses, corns, or ingrown nails with drugstore blades or medicated pads; keep follow-up appointments for her diabetes; and report any foot change early. Write the key points down - clients with neuropathy often retain less than they think.
