The 118°F Soak: A Diabetic Pedicure
Your 3:00 p.m. client is 62, has type 2 diabetes treated with metformin, and tells you her last A1c was 7.8%. She has booked the deluxe pedicure: soak, callus shaving, cuticle cutting, nail trimming, and a 15-minute foot massage. On intake she mentions she “can't really feel” the water temperature anymore. The right great toe is numb to light touch, the nail is thick and yellow-brown with debris under the free edge, and the skin between the fourth and fifth toes is peeling and white. She wants the callus on both heels shaved “down to smooth” and asks for the soak “as hot as you can get it - it feels good.” Your basin is filling and the thermometer reads 118°F. She has no open sore, and no redness or swelling.
1. Assess this client. Which findings change your plan, and what will you do and not do today?

Three findings change the plan.
- She cannot sense water temperature - that points to peripheral neuropathy. She cannot protect herself from a burn, so the thermometer, not her opinion, decides the water.
- The great toenail is thick, discolored, with subungual debris - that suggests a fungal infection needing a physician's diagnosis. Diagnosing and treating it is not your job.
- Peeling white skin between the fourth and fifth toes - suggests tinea pedis or maceration. The barrier is already compromised, and that skin tears easily.
What you do not do. No credo blade, no callus shaver, no cuticle cutting, no nippers on live tissue. A nick in a neuropathic foot can become an ulcer, and diabetic foot ulcers are a serious, sometimes limb-threatening problem. Do not take the callus “down to smooth.” Do not soak at 118°F - she cannot feel it and can be burned.
What you do. Check the water with a thermometer and keep it comfortably warm - roughly 100–105°F - and limit soak time. Inspect both feet in good light, between every toe. If you find any open area, redness, warmth, or swelling, stop and refer; no service.
Refer. The nail and the web space need a doctor or podiatrist. Say it plainly: “This looks like something a podiatrist should see. I can do a gentle cosmetic pedicure today, but I can't treat this.”
Then work gently with single-use file and buffer, one direction, light pressure, no thinning of the plate, no cutting.
2. Describe the modified pedicure step by step, including what you do differently about soaking, filing, cuticle work, drying, moisturizing, and massage.

Intake and inspection. Both feet, good light, every web space, note sensation and any break in the skin. Record what you see.
No sharp tools on the foot at all. Reduce callus only with a fine-grit paddle or pumice, in one direction, lightly, and only over intact skin. Stop if the skin reddens or thins.
Nails. Trim straight across with a nipper only if needed and only on a clear nail; file in one direction with light pressure. Do not probe under the free edge with a sharp tool.
Cuticles. Softener, then push back with a rubber or wooden stick. No cutting, no nipping, no clipping.
Soak. Short, thermometer-checked, warm rather than hot. Long soaks macerate skin that is already compromised.
Dry thoroughly, especially between the toes; leave the web spaces dry.
Moisturize the legs and the tops of the feet - not between the toes, where added moisture feeds fungus and maceration.
Massage. Light pressure, and skip it over any red, pale, cold, or numb area, or anywhere with a lesion. Neuropathic tissue does not report damage, so you have to be conservative for it.
Close the visit. Tell her what you saw, what you deliberately did not do, and why. Ask her to raise the nail and the web space at her next diabetes appointment. Document the findings, the modifications, and the referral.
3. She insists you shave the calluses and says her sister does it all the time. She then asks you to sign a form saying she refused a referral. How do you respond to each request?

The callus shaving: no, and not negotiable. Explain the mechanism, not just the rule: “With the feeling reduced in your feet, a slip with a blade is something you might not notice until it's an ulcer. That's why I won't use a blade on a diabetic foot.” Offer the alternative you can do - gentle abrasion over intact skin, moisturizer, a referral to a podiatrist who can safely reduce the callus. If she still wants the blade, she can get it somewhere else; that is her choice, not your obligation.
“My sister does it” is not a standard. A family habit is not a sanitation rule, a scope-of-practice rule, or a clinical judgment. Say so without insulting the sister.
The referral form. Different question. She is allowed to decline a referral, and an acknowledgment that she declined and that you explained the risk is reasonable to sign and keep - it documents the conversation. But that signature does not authorize the blade, and you should not let the two requests get bundled. Decline the shaving; document the referral discussion either way.
If she leaves. Fine. Note the visit, the findings, the refusal, and the referral. A lost ticket is cheaper than a burn or an ulcer.
