Dr. Karen Rebecca Hershenfield

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

Preventative Health Topics

• Weight Management & Obesity Prevention/Treatment: Supporting individuals in achieving and maintaining a healthy body weight through non-stigmatizing, patient-centered approaches that focus on sustainable lifestyle habits, improved metabolic health, and overall well-being rather than solely on rapid weight loss or restrictive dieting.
• Health Equity & Social Determinants of Health (SDOH) Discussion & Resource Navigation: A holistic approach to primary care that considers the broader social context of health and aims to reduce barriers to care and well-being by addressing SDOH.
• Driver's Medical Examinations (Routine, Age-Related, Commercial): Objective medical assessments for driving privileges, completed accurately according to regulatory requirements (fees typically apply as this is often an uninsured service). This may involve coordination with specialists if complex medical conditions impact driving ability.

Joint Muscle Pain

• Fibromyalgia & Other Widespread Chronic Pain Syndromes - Primary Care Diagnosis & Multimodal Management: Initial assessment and diagnosis of fibromyalgia or other widespread chronic pain syndromes based on established clinical criteria (e.g., ACR criteria for fibromyalgia), after appropriate investigation to rule out other underlying systemic inflammatory or medical conditions. Developing a comprehensive, multimodal management plan focusing on patient education about the condition (central sensitization, pain neurophysiology), promoting self-management, graded exercise therapy (low-impact aerobic, strength, flexibility, aquatic therapy), optimizing sleep hygiene, stress management techniques (mindfulness, relaxation, CBT principles), pain coping strategies, and judicious use of medications targeting central sensitization and associated symptoms (e.g., tricyclic antidepressants like amitriptyline, SNRIs like duloxetine/venlafaxine, gabapentinoids like gabapentin/pregabalin). Avoidance of long-term opioid therapy is generally emphasized.
• 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.
• 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: 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.

Common Chronic Conditions

• Anemia (Iron Deficiency, B12/Folate Deficiency - Chronic): Investigating causes of chronic or recurrent anemia (e.g., fatigue, pallor) through blood tests (CBC, iron studies, B12, folate, ferritin). Managing common types such as iron deficiency anemia (oral/IV iron supplementation, dietary advice) and vitamin B12 or folate deficiency anemia (supplementation), and identifying/addressing underlying causes (e.g., malabsorption, chronic blood loss, dietary insufficiency).
• Gastroesophageal Reflux Disease (GERD) & Peptic Ulcer Disease (PUD) - Chronic Management: Ongoing management of chronic GERD (acid reflux) and PUD, including lifestyle modifications (diet, weight, smoking cessation), prescription of acid-suppressing medications (PPIs, H2 blockers), H. pylori testing and eradication, and monitoring for complications or need for endoscopy.
• Asthma (All Ages) & Allergic Rhinitis: Working collaboratively with you (or your child) to achieve optimal asthma control, minimize symptoms (wheezing, coughing, shortness of breath), improve lung function, and reduce reliance on reliever medications.

Adult Common Health Issues

• Benign Prostatic Hyperplasia (BPH) - Symptom Management & Monitoring: Referral to urology for severe symptoms, complications (e.g., acute urinary retention, recurrent UTIs, bladder stones, renal impairment due to obstruction), or if surgical intervention (e.g., TURP) is being considered.
• 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).
• Anemia (Iron Deficiency, Vitamin B12/Folate Deficiency - Diagnosis & Management): Managing common types of nutritional anemia such as iron deficiency anemia (oral or intravenous iron supplementation, dietary advice to increase iron intake and absorption, investigation for source of chronic blood loss if suspected - e.g., GI bleed, heavy menses) and megaloblastic anemia due to vitamin B12 or folate deficiency (oral or parenteral supplementation, dietary counseling, investigation for underlying causes like pernicious anemia, malabsorption syndromes - celiac disease, Crohn's, post-gastric surgery, medication effects - metformin, PPIs).

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

• Cardiovascular & Metabolic Risk Assessment & Management: Identifying individuals at higher risk for heart attacks, strokes, or diabetes to implement early interventions and promote long-term health.
• Urgent Care for Non-Life-Threatening Conditions: Accessible care for urgent health needs that can be managed outside of an emergency department.
• Well-Child Visits & Developmental Surveillance (Infancy to Adolescence): Expert medical care and guidance for your child at every stage of development, promoting optimal physical, cognitive, and emotional health.
• Ordering & Interpretation of Diagnostic Imaging & Laboratory Testing: Interpreting test results in the context of your overall clinical picture, discussing their implications with you clearly, and arranging appropriate follow-up or further investigation.
• Occupational Health Aspects & Work-Related Health Concerns (Initial Assessment): Addressing health concerns that may be related to a patient's occupation, providing initial assessment for work-related injuries or illnesses, and completing necessary forms (e.g., fitness to work, return to work).
