Adult Common Health Issues

• Restless Legs Syndrome (RLS) - Initial Assessment & Management: Assessing patients presenting with symptoms suggestive of Restless Legs Syndrome (an urge to move the legs, usually accompanied by uncomfortable sensations, typically worse at rest/in the evening, and relieved by movement). This includes ruling out secondary causes (e.g., iron deficiency, kidney failure, pregnancy, certain medications).
• Anemia (Iron Deficiency, Vitamin B12/Folate Deficiency - Diagnosis & Management): Primary care approach to accurately diagnosing and effectively treating common forms of anemia to improve energy levels, cognitive function, exercise tolerance, and overall health. Referral to hematology for complex or unexplained anemia.
• Benign Prostatic Hyperplasia (BPH) - Symptom Management & Monitoring: Management includes lifestyle advice (fluid management, avoiding bladder irritants), behavioral therapies (timed voiding), and prescription of medications such as alpha-blockers (e.g., tamsulosin, alfuzosin) to relax prostate/bladder neck muscles, or 5-alpha-reductase inhibitors (e.g., finasteride, dutasteride) to shrink prostate volume. Monitoring for symptom improvement and medication side effects.
• 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.

Joint Muscle Pain

• 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).
• 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).
• 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).
• 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.

Dermatological Skin Conditions

• Psoriasis (Mild to Moderate Plaque Psoriasis - Initial Management): Initial diagnosis and management of mild to moderate plaque psoriasis, providing topical treatments (potent topical corticosteroids, vitamin D analogues like calcipotriol, combination products, coal tar preparations, emollients) and lifestyle advice (stress management, identifying triggers). Screening for psoriatic arthritis symptoms. Referral to dermatology for moderate to severe psoriasis (requiring phototherapy or systemic/biologic agents), psoriatic arthritis, or diagnostic uncertainty.
• Viral Skin Infections (Common Warts, Molluscum Contagiosum, Herpes Simplex, Herpes Zoster/Shingles): Providing effective treatment for various viral skin conditions to alleviate symptoms, shorten duration of outbreaks, prevent complications (like PHN or secondary bacterial infection), and reduce transmission where applicable.
• 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).
• Acne Vulgaris (Mild to Moderate) & Rosacea Management: Personalized treatment plans for acne and rosacea based on severity, skin type, patient preference, and potential impact on self-esteem.

Common Chronic Conditions

• Chronic Kidney Disease (CKD) - Early to Moderate Stages: Early detection, monitoring of kidney function (e.g., eGFR, urine ACR), management of risk factors that can worsen CKD (especially diabetes and hypertension), medication review to avoid nephrotoxic drugs, lifestyle counseling (dietary advice on protein, sodium, potassium), and timely referrals to nephrology for patients with early to moderate stage chronic kidney disease to slow progression and prevent complications.
• Thyroid Disorders (Hypothyroidism, Hyperthyroidism, Hashimoto's, Nodules): Diagnosis, treatment (e.g., levothyroxine for hypothyroidism, antithyroid drugs or referral for hyperthyroidism), and long-term monitoring of common thyroid conditions, including Hashimoto's thyroiditis, to ensure hormonal balance, manage symptoms effectively, and screen for complications like thyroid nodules or goiter. Includes initial investigation of thyroid abnormalities (e.g., ultrasound for nodules) and coordination with endocrinology for complex cases.
• 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): Managing chronic pain and stiffness associated with osteoarthritis in various joints (knees, hips, hands, spine), persistent mechanical low back or neck pain, and conditions like fibromyalgia. This involves a multimodal approach including education, exercise recommendations (strength, flexibility, low-impact aerobics), weight management, pain relief medications (topical, oral NSAIDs, acetaminophen, judicious use of other analgesics like gabapentinoids or TCAs for neuropathic/fibromyalgia components), joint injection considerations, and referrals to physiotherapy, rheumatology or pain clinics if needed.

Common Acute Conditions

• Allergic Reactions (Mild to Moderate - e.g., Hay Fever, Hives, Minor Food Allergy Symptoms): Diagnosing and managing common allergic reactions such as seasonal/perennial allergic rhinitis (hay fever), mild to moderate hives (urticaria), minor localized reactions to insect stings, and initial assessment of suspected mild food allergy symptoms. Does not include anaphylaxis management which is an emergency.
• Headaches (Tension-type, Migraine - Acute Symptomatic Relief): Providing prompt care for sudden or severe headaches, offering effective relief, and establishing a plan for ongoing management if headaches are recurrent or chronic.
• Urinary Tract Infections (UTIs - Cystitis, Pyelonephritis - uncomplicated initial): Management of bladder and kidney infections with appropriate antibiotics based on likely pathogens and local resistance patterns, along with advice on prevention strategies for recurrent UTIs and symptom relief.
