Foot care, nail care, and wound care are among the most frequently requested nursing services outside of healthcare facilities. Yet, for many people, accessing these services without waiting weeks in emergency rooms or without a family doctor remains a real challenge in the Quebec context. A painful ingrown toenail, a post-surgical wound requiring regular dressing changes, a chronic leg ulcer, or an invasive nail fungus are not trivial situations. If left untreated or poorly managed, they can lead to serious complications, particularly in individuals who are diabetic, immunocompromised, or have reduced mobility.
Clinique Omicron offers specialized nursing care for feet, nails, and wounds in several of its Quebec locations — performed by nurse clinicians trained in advanced wound care techniques, with on-site access to medical evaluations when clinically indicated.
Ingrown toenail and onychia: medical diagnosis and treatment
Ingrown toenail (onychocryptosis) occurs when the lateral edge of the nail—most often on the big toe—penetrates the adjacent skin, causing pain, local inflammation, and a risk of secondary infection. There are three progressive stages of severity: Stage 1 is characterized by pain upon pressure and slight redness without infection; Stage 2 presents with granulation tissue (fleshy buds) and serous or purulent discharge; Stage 3 involves frank tissue infection with suppuration, significant granuloma, and sometimes nail matrix deformity. Management depends on the stage. In Stage 1 and early Stage 2, conservative techniques may be sufficient: placement of a gutter or nail splint, drainage of the painful area, care of the periungual skin, and advice on proper nail trimming. In advanced Stage 2 and Stage 3, or in cases of recurrence, partial or total nail resection with destruction of the matrix under local anesthesia (phenolization) is the standard treatment, performed in a clinic under aseptic conditions.
Fungal nail infection (onychomycosis) is a fungal infection of the nail, caused in 90% of cases by dermatophytes (primarily Trichophyton rubrum) and, more rarely, by yeasts (Candida) or molds. It manifests as progressive thickening of the nail, discoloration (yellow, brown, or white), brittleness, and separation of the nail plate from the distal edge (onycholysis). The clinical diagnosis should ideally be confirmed by a mycological test (culture or PCR) before initiating prolonged antifungal treatment, as other conditions can mimic onychomycosis (nail psoriasis, chronic trauma, paronychia). Systemic treatment with terbinafine (250 mg/day for 6 weeks for fingernails, 12 weeks for toenails) offers the best mycological cure rates (70–80%), but requires liver monitoring in some patients. Topical treatments (amorolfine, ciclopirox, efinaconazole) are less effective as monotherapy but may be suitable for mild cases or as an adjunct to systemic treatment.
Wound care and dressing changes: wound types and treatment principles
The management of acute and chronic wounds is based on precise clinical principles that go beyond simple cleaning and dressing. The initial assessment of a wound includes evaluating its size, depth, location, and type of tissue present (necrotic, fibrinous, granulation, or epithelial tissue), assessing exudate (amount, appearance, odor), looking for signs of local infection (heat, peripheral redness, purulent exudate, odor, increasing pain, poor healing), or systemic infection (fever, lymphangitis), and the patient's medical context (diabetes, venous insufficiency, anticoagulant therapy, immunosuppression). The choice of dressing is guided by these elements: absorbent hydrocellular dressings for highly exuding wounds, hydrogels for dry or necrotic wounds requiring rehydration, alginates for bleeding wounds, silver dressings for infected or high-risk infected wounds, non-adherent interface dressings for fragile wounds.
Chronic wounds constitute a distinct category requiring specialized expertise. Venous leg ulcers—the most common type, accounting for 70% of chronic lower limb ulcers—result from chronic venous insufficiency with venous hypertension and require therapeutic compression (bandages or graduated compression stockings at 30–40 mmHg) in addition to local wound care, after ruling out underlying peripheral arterial disease by measuring the systolic pressure index. Arterial ulcers (peripheral arterial disease of the lower extremities) present a different clinical picture—painful wound, sharp edges, pale or necrotic base, absent distal pulses—and do not tolerate compression; they require revascularization. Diabetic foot ulcers constitute a relative clinical emergency because they heal poorly due to peripheral neuropathy (insensitivity to trauma), microangiopathy, and relative immunosuppression associated with poorly controlled diabetes—the risk of osteomyelitis and amputation warrants multidisciplinary management and close monitoring.
Foot care in the context of diabetes and vulnerability
The diabetic foot is one of the most dreaded complications of diabetes. In Canada, a diabetes-related amputation occurs every 30 minutes, and the vast majority of these amputations are preceded by a foot wound. Prevention relies on regular monitoring by a healthcare professional: a minimum annual foot examination (monofilament to test sensation, tuning fork for vibratory sensation, palpation of posterior tibial and dorsalis pedis pulses), identification of at-risk feet (deformities, calluses, dry skin, interdigital fungal infections), regular nail and callus care, education on daily foot inspection, skin hydration, appropriate shoe selection, and a prohibition on walking barefoot. Diabetic patients with established peripheral neuropathy are a priority population for regular podiatric nursing care, which allows for early detection of any lesion before it progresses to a chronic infected wound.
Frequently Asked Questions about Foot, Nail, and Wound Care
My ingrown toenail has been hurting a lot for a few days. Should I go to the emergency room or can I see a doctor at the clinic?
The vast majority of ingrown toenails, even painful ones, do not require a visit to the hospital emergency room—they can and should be managed in a primary care clinic. Emergencies are only justified if you show signs of severe infection: redness and warmth that rapidly spread beyond the toe into the foot, a red streak extending towards the ankle (lymphangitis), fever, or if you are diabetic or immunocompromised with a wound that concerns you—in these cases, a deep tissue infection (cellulitis, necrotizing fasciitis) must be quickly ruled out. Outside of these emergency situations, a clinic consultation allows for an accurate clinical assessment of the stage and any infection, appropriate treatment (conservative care or nail resection depending on the stage), a prescription for antibiotics if a bacterial infection is confirmed, and advice on preventing recurrence. Waiting and self-treating with home remedies simply risks allowing the infection to progress to the next stage.
My surgical wound requires regular dressing changes. How can I organize this follow-up at the clinic?
Surgical wounds often require regular dressing changes after returning home—the frequency varies depending on the type of surgery, the type of closure (sutures, staples, wound left open for secondary healing), and the wound's progression. These care services can be provided at Clinique Omicron by clinical nurses, by medical prescription, or as part of post-operative follow-up. It is helpful to bring the operative report or care instructions given at your hospital discharge to your first appointment, along with any specific prescribed supplies if your surgeon recommended a particular type of dressing. The clinical nurse will assess the wound at each visit, document its progress, and alert the doctor if signs of complications appear—infection, dehiscence (wound opening), or edge necrosis. The RAMQ generally covers wound care nursing services in the context of post-surgical follow-up; fees may apply depending on the situation and the type of materials used.
Can toenail fungus be treated at the clinic, or is it necessary to see a dermatologist?
Onychomycosis can certainly be diagnosed and treated in a primary care clinic — a dermatologist is not necessary for the vast majority of cases. The medical consultation at the clinic first allows for confirmation of the clinical diagnosis (and for a mycological sample to be taken if the presentation is not typical or before prescribing prolonged systemic treatment), evaluation of the extent of the infection and the number of affected nails, selection of the appropriate treatment (topical for mild to moderate forms without matrix involvement, systemic with terbinafine for more severe or resistant forms), and verification of contraindications and drug interactions before prescribing an oral antifungal. Terbinafine requires caution in patients with pre-existing liver disease and verification of interactions (CYP2D6 inhibitor: interactions with certain antidepressants, antiarrhythmics). A dermatology referral remains useful for atypical, resistant, or diagnostically uncertain cases, or when nail psoriasis is suspected.
