Dr. David Anthony Wan

Dr. David Anthony Wan provides comprehensive family medical care for a wide variety of health concerns affecting patients of all ages, including but not limited to:

Joint Muscle Pain

• Repetitive Strain Injuries (RSI), Tendinopathies & Work-Related Musculoskeletal Disorders (WRMSDs) - Initial Assessment & Conservative Management: A first point of contact for work-related or activity-induced repetitive strain injuries, guiding effective conservative management, facilitating return to function, and providing documentation for workplace accommodations if necessary. Referral to specialists (e.g., sports medicine, orthopedics, physiatry) if symptoms are persistent, severe, or require further investigation/intervention.
• Fibromyalgia & Other Widespread Chronic Pain Syndromes - Primary Care Diagnosis & Multimodal Management: Working collaboratively with individuals experiencing chronic widespread pain to develop personalized self-management strategies, set realistic functional goals, and coordinate care effectively with other healthcare providers such as physiotherapists, occupational therapists, psychologists, and rheumatologists (for diagnostic confirmation or complex cases).
• Gout & Pseudogout (Crystal Arthropathies) - Acute Attack Management & Chronic Prevention Strategies: Diagnosing (often clinical, supported by serum uric acid levels; joint aspiration for crystal analysis if diagnostically uncertain or to rule out septic arthritis) and managing acute gout or pseudogout attacks with appropriate anti-inflammatory medications (NSAIDs like naproxen/indomethacin, colchicine, oral or intra-articular corticosteroids).
• Polymyalgia Rheumatica (PMR) - Diagnosis, Management & Monitoring (Often with Rheumatology Co-Management): Long-term management of PMR involves a very slow and gradual tapering of corticosteroids over 1-2 years (or longer), carefully monitoring for clinical relapse (recurrence of symptoms) and adjusting steroid dose accordingly. Also includes monitoring for and managing potential corticosteroid side effects (e.g., osteoporosis - bone protection with calcium/vitamin D, bisphosphonates if needed; hyperglycemia; hypertension; weight gain; mood changes; skin fragility).

Adult Common Health Issues

• Allergic Conjunctivitis & Dry Eye Syndrome - Primary Care Management: Helping patients find relief from itchy, irritated, or dry eyes through appropriate primary care interventions and guidance.
• Helicobacter pylori (H. pylori) Infection - Testing & Eradication Therapy: Confirmation of eradication testing post-treatment to ensure successful clearance of the infection and reduce risks of H. pylori-related gastroduodenal diseases.
• Restless Legs Syndrome (RLS) - Initial Assessment & Management: Providing initial management strategies for RLS, including lifestyle modifications (e.g., regular exercise, good sleep hygiene, avoiding caffeine/alcohol close to bedtime), checking and correcting iron deficiency (ferritin levels), and considering pharmacological options (e.g., dopamine agonists like pramipexole/ropinirole, gabapentin enacarbil) for moderate to severe, frequent symptoms that significantly impact sleep or quality of life. Referral to neurology or sleep specialist for complex or refractory cases.

Dermatological Skin Conditions

• Viral Skin Infections (Common Warts, Molluscum Contagiosum, Herpes Simplex, Herpes Zoster/Shingles): Diagnosing and managing common viral skin infections. This includes common/plantar warts and molluscum contagiosum (observation, cryotherapy, topical agents like salicylic acid or cantharidin). For Herpes Simplex Virus (HSV - cold sores/fever blisters, genital herpes): antiviral therapy (acyclovir, valacyclovir, famciclovir) for acute outbreaks or suppressive therapy for frequent recurrences, plus counseling on transmission. For Herpes Zoster (Shingles): prompt antiviral therapy to reduce severity/duration and risk of post-herpetic neuralgia (PHN), along with pain management. Shingles vaccination advice for eligible adults.
• Psoriasis (Mild to Moderate Plaque Psoriasis - Initial Management): Helping patients manage the symptoms of psoriasis (scaling, plaques, itchiness) and reduce skin inflammation through effective topical therapies and supportive care.
• Eczema (Atopic Dermatitis), Contact Dermatitis & Seborrheic Dermatitis: Diagnosing and managing various forms of eczema/dermatitis, including atopic dermatitis (the most common type, often starting in childhood), irritant/allergic contact dermatitis (identifying and avoiding triggers), and seborrheic dermatitis (affecting scalp, face, chest). Management focuses on skincare education (frequent emollients, gentle cleansers, lukewarm baths), trigger identification and avoidance, topical corticosteroids (appropriate potency for site and severity), topical calcineurin inhibitors (TCIs like tacrolimus, pimecrolimus), and antihistamines for itch relief. Referral for patch testing or to dermatology for severe or refractory cases.

Common Acute Conditions

• Upper Respiratory Tract Infections (URTIs - Colds, Flu, Sinusitis, Pharyngitis): Addressing symptoms such as cough, sore throat (including rapid strep testing where available), nasal congestion, facial pain/pressure, and fever associated with common URTIs.
• Lower Respiratory Tract Infections (Acute Bronchitis, Community-Acquired Pneumonia): Assessment and treatment for acute chest infections like acute bronchitis or mild to moderate community-acquired pneumonia, including determining the need for antibiotics based on clinical assessment and guidelines, and monitoring recovery closely.
• Common Acute Skin Conditions (Rashes, Infections, Bites, Minor Burns): Managing various acute dermatological conditions with appropriate topical or oral medications (antibiotics, antifungals, corticosteroids, antihistamines) to alleviate itching, redness, pain, swelling, and discomfort.
• Urinary Tract Infections (UTIs - Cystitis, Pyelonephritis - uncomplicated initial): Prompt diagnosis (e.g., urinalysis, urine culture if needed) and treatment for uncomplicated urinary tract infections such as cystitis (bladder infection) and initial assessment/management of suspected uncomplicated pyelonephritis (kidney infection) to alleviate discomfort (dysuria, frequency, urgency, flank pain) and prevent complications.

Preventative Health Topics

At Memory & Aging Canada, family medicine is centered on a collaborative partnership to help individuals like you achieve significant improvements in your health, manage ongoing conditions effectively, and enhance your overall well-being. Dr. Wan frequently works with patients towards goals such as:

• Managing a tick bite and concerns about Lyme disease, especially after hiking effectively is a priority for Dr. Wan. The aim is feeling much more confident and competent in managing minor common illnesses at home for themselves or their children after receiving clear, practical instructions and valuable anticipatory guidance from Dr. Wan, which helps patients get back to enjoying skillfully and creatively cooking a wide variety of nutritious, flavorful, and delicious meals from scratch for themselves, their partners, and their families on a regular basis, finding joy in the process.
• For patients where wanting reliable advice and a realistic plan on how to eat healthier, manage their weight better, or start exercising safely is a concern, Dr. Wan focuses on plans that lead to their children being notably less fearful and more cooperative during doctor visits and even immunizations, specifically because of Dr. Wan's consistently gentle, patient, and child-friendly communication approach, supporting their ability to being able to comfortably stand for reasonably extended periods when necessary, for example, while cooking intricate meals, attending a standing-room-only event, actively participating in a workshop, or waiting patiently in unavoidable queues.
• Many seek Dr. Wan's help for a nagging low backache that's making it hard to sit, stand, or even sleep comfortably. The collaborative goal is navigating complex family health dynamics, intergenerational health concerns, or challenging caregiver stress with insightful advice, valuable resources, and compassionate support facilitated by Dr. Wan, allowing a return to valued activities like consistently sleeping soundly and deeply through the entire night on a regular basis and waking up feeling genuinely refreshed, fully restored, and ready to embrace the day ahead with clarity.
• The focus for patients with discussing the pros and cons of hormone replacement therapy for menopause at Dr. Wan's practice is achieving having their unique cultural background, personal values, spiritual beliefs, and communication preferences consistently respected and thoughtfully incorporated into their personalized healthcare plan by an attentive and culturally sensitive Dr. Wan, facilitating a return to meaningful activities like joyfully and responsibly taking care of beloved family pets, which includes activities like daily walking, regular feeding, grooming, active playtime, and providing necessary veterinary care.

Do I need a referral to see a family doctor (Family Doctor) in ON?

How do I get a prescription refilled by Dr. Wan?

For most refills, contact your pharmacy at least 5-7 days before you run out of medication. Your pharmacy can fax a refill request to Dr. Wan's office. Allow 2-3 business days for processing.

What is 'continuity of care' and why is it important with a family doctor like Dr. Wan?

Continuity of care means your family doctor, Dr. Wan, sees you for your health needs on an ongoing basis.
