Treatment of Hip Ache and Pain at Night
For hip pain at night, begin with paracetamol (acetaminophen) up to 4 grams daily as first-line therapy, combined with a structured exercise program lasting at least 3 months, and consider NSAIDs at the lowest effective dose if paracetamol is insufficient. 1
Initial Diagnostic Approach
Before initiating treatment, proper diagnosis is essential:
- Obtain plain radiographs (AP pelvis and hip views) as the first imaging study to screen for common disorders like osteoarthritis, fractures, or bone tumors 1, 2, 3
- If radiographs are negative or equivocal and symptoms persist, MRI hip without IV contrast is the next appropriate imaging study (rated 9/9 by ACR) 3
- Image-guided diagnostic injection into the hip joint can confirm if pain originates from the hip joint itself versus referred sources 3
Pharmacological Treatment Algorithm
First-Line: Paracetamol (Acetaminophen)
- Paracetamol up to 4 g/day is the oral analgesic of first choice for mild-moderate pain due to its efficacy and safety profile 1
- This is the preferred long-term oral analgesic if successful 1
Second-Line: NSAIDs
- Add or substitute NSAIDs at the lowest effective dose if paracetamol provides inadequate relief 1
- For patients with increased gastrointestinal risk, use non-selective NSAIDs plus gastroprotective agent, or a selective COX-2 inhibitor 1
- NSAIDs should be used at the lowest dose possible for the shortest time needed due to cardiovascular and gastrointestinal risks 4
Third-Line: Opioid Analgesics
- Opioid analgesics (with or without paracetamol) are useful alternatives when NSAIDs are contraindicated, ineffective, or poorly tolerated 1
Adjunctive Options
- Symptomatic slow-acting drugs for osteoarthritis (SYSADOA) including glucosamine sulfate, chondroitin sulfate, and others have symptomatic effect with low toxicity, though effect sizes are small 1, 5
Non-Pharmacological Treatment (Essential Component)
Exercise-Based Treatment
- Exercise-based treatments are strongly recommended (moderate evidence, consensus score 9/9) 1
- Exercise programs should be at least 3 months duration to achieve optimal benefit 1
- Include hip, trunk, and functional strengthening components with resistance exercises 1
- Exercise descriptors should specify load magnitude, repetitions, sets, duration, and progression 1
Additional Non-Pharmacological Interventions
- Regular patient education is essential 1
- Weight reduction if obese or overweight 1
- Assistive devices (walking stick, insoles) as appropriate 1
- Physical activity and sport participation are recommended even with hip-related pain 1
Interventional Treatment Options
Intra-articular Corticosteroid Injections
- Image-guided intra-articular steroid injections (ultrasound or x-ray guided) may be considered for patients with flare unresponsive to analgesics and NSAIDs 1, 3
- Typical doses: 5-15 mg for larger joints like the hip 6
- Strict aseptic technique is mandatory 6
Monitoring and Shared Decision-Making
- Use patient-reported outcome measures (PROMs), physical impairment measures, and psychosocial factors to monitor treatment response 1
- Discuss patient expectations and use shared decision-making throughout the treatment process 1
Important Clinical Considerations
Nocturnal Pain Characteristics
- Patients with hip osteoarthritis frequently report nocturnal pain that may differ in character from daytime pain 7, 8
- Nocturnal pain correlates with worse hip function scores and reduced sleep quality 7
- Patients with nocturnal pain often have higher pain intensity scores at night compared to daytime 8
Common Pitfalls to Avoid
- Do not proceed to advanced imaging without obtaining plain radiographs first 1, 3
- Do not overlook referred pain from lumbar spine, sacroiliac joints, or knee as potential sources 1, 9
- Screen patients with poor hip metrics for sleep disturbance, as this significantly impacts quality of life 7
- Avoid peripheral nerve blocks (e.g., obturator nerve) as these are experimental with insufficient evidence 3
When to Consider Surgical Referral
- Joint replacement should be considered for patients with radiographic evidence of hip OA who have refractory pain and disability despite conservative management 1
- Osteotomy and joint-preserving procedures should be considered in young adults with symptomatic hip OA, especially with dysplasia or deformity 1
