Dr. Bonnie Lynn Marshall

Dr. Bonnie Lynn Marshall 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

• Mechanical Low Back & Neck Pain (Acute, Subacute, Chronic - Uncomplicated): Assessment and management of non-specific (mechanical) low back pain and neck pain, which accounts for the majority of spinal pain presentations. This includes taking a thorough history, performing a focused physical examination to rule out 'red flag' conditions (e.g., fracture, infection, malignancy, cauda equina syndrome), providing reassurance about the generally favorable prognosis of acute pain, and advising on pain relief (acetaminophen, NSAIDs, short-term muscle relaxants if severe spasm), maintaining activity as tolerated (avoiding prolonged bed rest), heat/cold application, and self-care strategies. For subacute or chronic pain, emphasis on active therapies (exercise, physiotherapy referral), addressing psychosocial factors (yellow flags), and promoting functional restoration.
• Repetitive Strain Injuries (RSI), Tendinopathies & Work-Related Musculoskeletal Disorders (WRMSDs) - Initial Assessment & Conservative Management: Providing advice on activity modification (relative rest, avoiding aggravating activities), ergonomic adjustments (workstation setup, tool use), simple analgesia (NSAIDs - oral/topical, acetaminophen), ice/heat application, and appropriate referral to physiotherapy or occupational therapy for specific exercises (stretching, strengthening), manual therapy, splinting, and further rehabilitation or prevention strategies.
• Polymyalgia Rheumatica (PMR) - Diagnosis, Management & Monitoring (Often with Rheumatology Co-Management): Recognizing the characteristic clinical presentation of Polymyalgia Rheumatica (PMR) in older adults (typically age >50 years) – symmetrical morning stiffness and aching in the shoulders, neck, and pelvic girdle – often associated with significantly elevated inflammatory markers (ESR, CRP). Initiating treatment with low-dose corticosteroids (e.g., prednisone 12.5-25 mg daily) which usually results in a rapid and dramatic improvement in symptoms, thus supporting the diagnosis. Vigilantly screening for and differentiating from Giant Cell Arteritis (GCA/Temporal Arteritis), which can co-exist with PMR (or occur independently) and requires urgent higher-dose steroid therapy and specialist (rheumatology/ophthalmology) referral to prevent irreversible vision loss.
• Gout & Pseudogout (Crystal Arthropathies) - Acute Attack Management & Chronic Prevention Strategies: Providing long-term management strategies for chronic gout to prevent recurrent attacks and complications (e.g., tophi, chronic gouty arthropathy, kidney stones), including detailed lifestyle advice (dietary modifications - reducing purine-rich foods such as red meat/organ meats/shellfish, limiting alcohol especially beer and spirits, avoiding sugary drinks/high-fructose corn syrup; hydration; weight management if overweight/obese) and initiating/managing urate-lowering therapy (ULT) such as allopurinol or febuxostat to achieve and maintain target serum uric acid levels (typically <360 µmol/L or <300 µmol/L if tophi present). Monitoring for medication side effects, adherence, and regular serum uric acid levels.

Dermatological Skin Conditions

• Viral Skin Infections (Common Warts, Molluscum Contagiosum, Herpes Simplex, Herpes Zoster/Shingles): Primary care management for common skin infections caused by viruses, including patient education on the nature of these infections and strategies for managing recurrences.
• Benign Skin Lesion Assessment & Management (Skin Tags, Seborrheic Keratoses, Cysts, Lipomas): Differentiating between benign and potentially suspicious skin lesions is a key role, with prompt biopsy or referral to dermatology if any features suggest skin cancer (melanoma, basal cell carcinoma, squamous cell carcinoma).
• Fungal Skin, Nail & Hair Infections (Tinea species, Candidiasis, Onychomycosis): Managing common mycotic infections to resolve symptoms (itching, scaling, discoloration, inflammation), prevent spread to others, and restore healthy skin and nails.

Adult Common Health Issues

• Anemia (Iron Deficiency, Vitamin B12/Folate Deficiency - Diagnosis & Management): Investigating causes of anemia (e.g., symptoms like fatigue, pallor, dyspnea on exertion, dizziness, palpitations, restless legs) through thorough history (diet, medications, menstrual history, GI symptoms), physical examination, and targeted blood tests (Complete Blood Count - CBC with differential and red cell indices, iron studies including ferritin, serum vitamin B12, serum folate, reticulocyte count, LDH, bilirubin if hemolysis suspected).
• Helicobacter pylori (H. pylori) Infection - Testing & Eradication Therapy: Testing for Helicobacter pylori infection in appropriate clinical contexts (e.g., patients with peptic ulcer disease, certain types of gastritis, dyspepsia in high-prevalence areas, or family history of gastric cancer) using non-invasive methods like urea breath test, stool antigen test, or serology (less reliable for active infection).
• Benign Prostatic Hyperplasia (BPH) - Symptom Management & Monitoring: Assessing and managing lower urinary tract symptoms (LUTS) in aging men commonly due to benign prostatic hyperplasia (BPH). Symptoms include urinary frequency, urgency, nocturia (waking at night to urinate), weak or intermittent stream, hesitancy, straining, and incomplete bladder emptying. Assessment involves history, International Prostate Symptom Score (IPSS) questionnaire, digital rectal exam (DRE) to assess prostate size/consistency, urinalysis to rule out UTI, and serum PSA discussion (for prostate cancer screening context).

Common Chronic Conditions

• Irritable Bowel Syndrome (IBS) - Primary Care Management: Diagnosing IBS based on symptom criteria after ruling out other conditions, and providing primary care management strategies including dietary advice (e.g., low FODMAP diet introduction, fiber management), lifestyle modifications, stress reduction techniques, and symptomatic treatment for abdominal pain, bloating, diarrhea, and/or constipation.
• Anemia (Iron Deficiency, B12/Folate Deficiency - Chronic): Primary care approach to identifying and managing deficiencies or chronic conditions that lead to persistent anemia.
• Osteoarthritis & Other Chronic Musculoskeletal Pain (e.g., Chronic Back/Neck Pain, Fibromyalgia): Developing personalized strategies to reduce chronic joint and muscle pain, improve mobility and function, enhance coping mechanisms, and improve overall quality of life for those living with conditions like arthritis, persistent back pain or fibromyalgia.

This list offers some examples of common conditions managed in family practice. A diagnosis is always based on an individual assessment by Dr. Marshall. If your specific health concern isn't listed, please contact the clinic to discuss your needs.

• Chronic Pain Management (Musculoskeletal, Neuropathic - Primary Care Approach): Initial assessment and development of a management plan for chronic pain conditions (e.g., osteoarthritis, chronic low back pain, fibromyalgia, neuropathic pain), employing a multimodal approach including lifestyle advice, exercise recommendations, non-opioid and judicious opioid medication management, pain education, and referrals to specialized pain clinics, physiotherapy, or other therapies.
• Weight Management & Healthy Weight Strategies: Collaboratively discussing healthy weight goals based on BMI, waist circumference, and overall health status. Providing guidance on balanced nutrition, portion control, mindful eating, regular physical activity, behavioral strategies (e.g., goal setting, self-monitoring, addressing emotional eating), and addressing underlying factors contributing to weight issues. Medical options may be discussed if appropriate based on guidelines and individual assessment.
• Driver's Medical Examinations & Other Third-Party Medical Reports: Conducting medical examinations and completing forms required for driver's licenses (commercial, age-related), insurance purposes, employment, school, disability applications, or travel (fees typically apply for non-insured services).
• Fungal, Viral & Bacterial Skin Infections: Managing common cutaneous infections to resolve symptoms and prevent spread or recurrence.
• Ordering & Interpretation of Diagnostic Imaging & Laboratory Testing: Utilizing appropriate diagnostic investigations judiciously to ensure accurate medical assessment, informed decision-making, and efficient use of healthcare resources.

At Joseph Brant Hospital, 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. Marshall frequently works with patients towards goals such as:

• Dr. Marshall often sees patients whose their teenager needing a confidential space to discuss sensitive health concerns like sexual health or mental well-being limits their enjoyment of successfully pursuing further formal education, challenging vocational training programs, or self-directed learning initiatives to achieve important personal growth objectives or significant professional aspirations. The goal of care is to achieve developing a deeply trusted, respectful, and enduring long-term therapeutic relationship with their dedicated and accessible primary care physician, Dr. Marshall, built on open communication and mutual respect and restore their active lifestyle.
• When difficulty concentrating at work or school that's new for them impacts daily life, Dr. Marshall helps patients strive for receiving a timely diagnosis of a previously unrecognized condition like obstructive sleep apnea, celiac disease, or hypothyroidism through Dr. Marshall's astute clinical screening and appropriate referral for confirmatory testing, leading to effective treatment and significantly improved quality of life, making activities such as boldly taking on new, exciting challenges or ambitious, multi-stage projects either at work or in their personal life with a strong sense of self-efficacy, physical capability, and mental preparedness possible again.
• If their elderly relative seeming more confused or withdrawn lately is preventing you from actively participating in ongoing professional development activities, industry conferences, or learning new, marketable skills for their current career path or potential future career transitions, Dr. Marshall can help. The aim is to achieve their elderly parents or relatives receiving thoughtful, patient, dignified, and age-appropriate comprehensive care from Dr. Marshall that demonstrably enhances their functional abilities, safety, and overall quality of life in their later years through personalized family medicine care.
• For patients where feeling generally 'unwell' or 'off' without a clear reason for a while is a concern, Dr. Marshall focuses on plans that lead to feeling genuinely reassured, thoroughly well-informed about all aspects of their condition, and like an empowered, active partner in all decisions regarding their health status, treatment options, and long-term care strategies discussed with Dr. Marshall, supporting their ability to passionately playing their favorite competitive or recreational sport – be it soccer on weekends, league hockey, a round of golf, a tennis match, or pickup basketball – regularly, skillfully, and without the constant dread of debilitating pain, flare-ups, or fear of re-injury.

Your personalized healthcare plan, developed in discussion with Dr. Marshall, will be thoughtfully designed to help you reach your specific functional, preventative, and wellness objectives. She believes in empowering patients with the knowledge and support needed to take an active role in their health journey.

It’s about being proactive with your health rather than just treating problems as they arise, and Dr. Marshall can help guide you in these efforts.

I have multiple health problems. How does Dr. Marshall handle complex care?
