Dermatological Skin Conditions

• 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.
• Fungal Skin, Nail & Hair Infections (Tinea species, Candidiasis, Onychomycosis): Diagnosis (clinical, skin scraping/KOH preparation, fungal culture if needed) and treatment of common superficial fungal infections including tinea corporis (ringworm), tinea pedis (athlete's foot), tinea cruris (jock itch), tinea capitis (scalp ringworm - requires oral therapy), tinea versicolor (pityriasis versicolor), cutaneous candidiasis (e.g., intertrigo, diaper rash), and onychomycosis (fungal nail infections). Treatment involves topical antifungal creams/lotions/shampoos (e.g., clotrimazole, miconazole, terbinafine, ketoconazole) or oral antifungal medications (e.g., terbinafine, itraconazole, fluconazole) for more extensive, resistant, or nail/hair infections.
• Acne Vulgaris (Mild to Moderate) & Rosacea Management: Helping adolescents and adults manage these common and often distressing inflammatory skin conditions effectively to improve skin appearance, reduce symptoms (redness, papules, pustules, flushing), prevent scarring (acne), and enhance quality of life.
• 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.

Joint Muscle Pain

• 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.
• Repetitive Strain Injuries (RSI), Tendinopathies & Work-Related Musculoskeletal Disorders (WRMSDs) - Initial Assessment & Conservative Management: Initial assessment, diagnosis, and conservative management of musculoskeletal pain and dysfunction related to repetitive tasks, sustained awkward postures, or ergonomic factors at work or during hobbies. This includes common conditions like carpal tunnel syndrome (mild-moderate), de Quervain's tenosynovitis, epicondylitis (tennis/golfer's elbow), trigger finger/thumb, rotator cuff tendinopathy, patellar tendinopathy, Achilles tendinopathy, and non-specific arm/neck/shoulder pain attributable to overuse.
• 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.
• 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).

Preventative Health Topics

• Comprehensive Lifestyle Counseling (Diet, Exercise, Sleep, Stress Reduction): Supporting your efforts to adopt and maintain healthier habits across multiple domains of life for a better quality of life, increased resilience, and proactive disease prevention through shared goal setting and ongoing support.
• Infectious Disease Prevention & Outbreak Management Support (Community Level): Promoting individual and community resilience against infectious diseases through education, vaccination, and adherence to public health measures.
• Health Equity & Social Determinants of Health (SDOH) Discussion & Resource Navigation: Advocating for patients facing health inequities and working to connect them with resources that can improve their overall health outcomes and reduce disparities.

Adult Common Health Issues

• 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.
• 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).
• 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: Prescribing evidence-based eradication therapy regimens (typically involving a combination of antibiotics and a proton pump inhibitor - PPI) for confirmed H. pylori infection, according to local guidelines and resistance patterns. Providing patient education on medication adherence and potential side effects.
