One-liner#
Adult/geriatric approach to multiple joint pains: separate inflammatory arthritis from OA/mechanical pain and centralized pain, identify time-sensitive mimics (septic arthritis, PMR/GCA), and start a targeted workup and referral plan.

Red flags / send to ED#
- Fever/systemic illness with a hot swollen joint (suspected septic arthritis)
- New severe headache, jaw claudication, or vision changes with shoulder/hip girdle pain (possible GCA)
- Rapidly progressive weakness, inability to stand/walk, or neurologic deficits
Key history#
- Inflammatory pattern: morning stiffness >30–60 min, improvement with movement, night pain
- Mechanical pattern: brief stiffness, pain worse with activity/late day, no true swelling
- Joint distribution: symmetric small joints (RA), DIP involvement (PsA/OA), axial/back pain (spondyloarthritis)
- True swelling vs “puffy” sensation; episodic attacks (crystal)
- Extra-articular clues: psoriasis/nail changes, uveitis, IBD symptoms, oral ulcers, rash, Raynaud, sicca
- Recent viral illness, new meds, travel/tick exposure (regional)
- Age >50 with shoulder/hip girdle pain and stiffness (PMR screen) and GCA symptoms
Focused exam#
- Identify synovitis: warmth, boggy swelling, effusion, pain with passive ROM
- Count affected joints; note symmetry and small vs large joint predominance
- Skin/nails (psoriasis), enthesitis (heel/Achilles), dactylitis (“sausage digit”)
- Proximal muscle strength and tenderness (PMR vs myositis patterns)
Differential (quick pattern recognition)#
Common/likely (outpatient)#
| Diagnosis | Keywords patients use | Key clues | Focused exam clues | Initial next step |
|---|---|---|---|---|
| Osteoarthritis (multi-joint) | “Achy,” “stiff but loosens fast” | Brief AM stiffness; activity-related | Bony enlargement/crepitus; minimal warmth | Conservative OA plan; targeted x-rays if needed |
| Rheumatoid arthritis | “Swollen knuckles,” “morning stiffness” | Symmetric small joints; inflammatory pattern | MCP/PIP synovitis | ESR/CRP + RF/anti-CCP; early rheum referral |
| Psoriatic arthritis | “Swollen fingers,” “back/heel pain” | Psoriasis/nail changes; DIP/enthesitis | Dactylitis, enthesitis | ESR/CRP; rheum referral |
| Polymyalgia rheumatica | “Shoulders and hips ache,” “stiff in morning” | Age >50; proximal girdle pain | Pain with ROM; strength preserved | ESR/CRP; assess for GCA; treat per protocol |
| Fibromyalgia/centralized pain | “Hurts everywhere,” “brain fog,” poor sleep | Widespread pain; fatigue; noninflammatory | No synovitis | Education + graded activity + sleep focus |
| Viral/reactive arthritis | “Started after a virus” | Recent viral/GI/GU illness | Variable | Supportive care; targeted tests if indicated |
Can’t-miss / urgent#
| Diagnosis | Keywords patients use | Key clues | Focused exam clues | Initial next step |
|---|---|---|---|---|
| Septic arthritis | “Hot,” “feels sick” | Fever/toxic; single joint often worst | Severe pain with passive ROM | ED now; aspiration/cultures + antibiotics per protocol |
| Giant cell arteritis (with/without PMR) | “New headache,” “jaw pain,” vision symptoms | Age >50; systemic symptoms | Temporal tenderness (may be absent) | Same-day urgent evaluation; treat per protocol |
Workup#
- Avoid shotgun testing; match tests to the clinical pattern.
- If inflammatory arthritis is suspected:
- ESR/CRP, CBC/CMP
- RF + anti-CCP for RA pattern
- Consider ANA only if systemic autoimmune features are present (rash, ulcers, Raynaud, serositis, cytopenias).
- If PMR/GCA suspected: ESR/CRP urgently and follow local protocol for treatment/referral (do not delay if vision symptoms).
- If crystal arthritis is part of the story: prioritize aspiration when a joint is actively swollen and diagnosis is uncertain.
- Imaging: targeted x-rays when they change management (baseline OA; hands/feet if inflammatory arthritis suspected and helpful locally).
Important caveats:
- Seronegative RA exists: ~20% of RA patients are RF and anti-CCP negative; if clinical picture is convincing (symmetric small joint synovitis, prolonged morning stiffness), refer to rheumatology anyway
- Normal ESR/CRP doesn’t rule out inflammatory arthritis: some patients have active synovitis with normal markers; clinical exam trumps labs
- ANA is often positive in healthy people: don’t order unless systemic features are present; a positive ANA without clinical context causes more confusion than clarity
Initial management#
- Symptom control while workup/referral proceeds—see medication tables below.
- Avoid prolonged empiric steroids before clarifying diagnosis (can mask infection); exceptions exist (e.g., high suspicion GCA per protocol).
- Early referral when inflammatory arthritis is suspected (better outcomes with early treatment).
Symptomatic treatment options#
| Drug | Dose | Contraindications | Monitoring | Cost | Notes |
|---|---|---|---|---|---|
| Acetaminophen | 650–1000 mg q6–8h; max 3 g/day | Severe hepatic impairment | LFTs if prolonged use | $ | Safe first-line; limited efficacy for inflammatory pain |
| Naproxen | 250–500 mg q12h; max 1000 mg/day | CKD, GI bleed, HF, anticoagulation | Cr, BP if prolonged | $ | Good for inflammatory pain; limit duration |
| Ibuprofen | 400–600 mg q6–8h with food; max 2400 mg/day | Same as naproxen | Same as naproxen | $ | Shorter half-life than naproxen |
| Meloxicam | 7.5–15 mg daily | Same as naproxen | Same as naproxen | $ | Once-daily; COX-2 preferential |
| Diclofenac gel 1% | Apply 4 g to affected joints QID | Avoid on broken skin | Minimal systemic absorption | $$ | Good for localized OA; lower systemic risk |
PMR treatment (if diagnosis secure; verify local protocol)#
| Drug | Dose | Contraindications | Monitoring | Cost | Notes |
|---|---|---|---|---|---|
| Prednisone | 12.5–25 mg daily; taper over months | Uncontrolled DM, active infection | Blood glucose, BP, bone health | $ | Dramatic response expected within days; if no response, reconsider diagnosis |
PMR steroid pearls:
- Start at 12.5–25 mg (lower end if uncomplicated); higher doses suggest GCA or alternative diagnosis
- Expect >70% improvement within 1 week; if not, reconsider diagnosis
- Plan for slow taper over 1–2 years; relapses common
- Address bone protection: calcium, vitamin D, consider bisphosphonate if prolonged use expected
When NOT to start steroids empirically:
- Fever or concern for infection (steroids mask septic arthritis)
- Unclear diagnosis without rheumatology input
- Suspected GCA with vision symptoms (needs urgent high-dose steroids per protocol, not PMR dosing)
Management by diagnosis#
Suspected inflammatory arthritis (RA/PsA/spondyloarthritis)#
- Education: inflammatory arthritis is treatable; early specialist care prevents joint damage.
- Treatment: start symptom control measures and complete targeted labs; coordinate early rheumatology referral.
- Follow-up: 2–4 weeks to review labs and confirm referral plan (sooner if rapid progression).
Polymyalgia rheumatica (suspected)#
- Education: common after age 50; often dramatic stiffness and proximal pain; screen for GCA symptoms.
- Treatment: follow local protocol (often steroid-responsive); address bone protection and monitoring if steroids used.
- Follow-up: within 1–2 weeks after starting therapy (or sooner if GCA symptoms).
Osteoarthritis (multi-joint)#
- Education: activity and strength drive function; imaging severity doesn’t always match pain.
- Treatment: exercise/PT, weight optimization, topical NSAID, joint protection strategies.
- Follow-up: 6–12 weeks.
Fibromyalgia/centralized pain#
- Education: pain amplification is real; improvement comes from sleep, movement, and stress modulation.
- Treatment: graded aerobic activity, sleep optimization, CBT/behavioral strategies; meds only as adjunct per local practice.
- Follow-up: 4–8 weeks.
Follow-up#
- Reassess in 2–4 weeks to review labs, refine differential, and ensure referral is in place if inflammatory disease suspected.
- Urgent return for fever, a hot swollen joint, new neurologic deficits, or new headache/jaw claudication/vision changes.
Patient instructions#
- Track which joints are affected, morning stiffness duration, and triggers; bring this to follow-up.
- Stay gently active; avoid prolonged immobility during flares.
- Use over-the-counter pain options if safe for you.
- Seek urgent care now for fever with a hot swollen joint, or new headache/jaw pain/vision changes.
Smartphrase snippets#
