Treatment of Upper Back Myofascial Pain Syndrome
Begin with a structured rehabilitation program combining stretching exercises, NSAIDs or acetaminophen for pain control, and manual therapy, while avoiding trigger point injections and opioids due to insufficient evidence and potential harm. 1, 2
First-Line Conservative Management
Exercise Therapy (Primary Treatment)
- Prescribe daily stretching exercises performed 9 times per day targeting the upper trapezius and affected muscle groups, as this forms the foundation of effective treatment 3, 4
- Progress to eccentric strengthening exercises once acute pain subsides, as these reverse degenerative changes in affected muscles 5
- Include scapular stabilization exercises to address underlying biomechanical dysfunction 6
- Avoid overhead pulley exercises as they may worsen pain through uncontrolled movement patterns 6
Pharmacological Management
- Start with acetaminophen (first-line) or NSAIDs (ibuprofen 400mg every 4-6 hours) for short-term pain relief, recognizing these provide symptomatic relief but do not alter long-term outcomes 2, 5
- Consider topical NSAIDs (diclofenac gel) as preferred over oral formulations when pain is localized, offering similar efficacy with fewer systemic side effects 5
- Add muscle relaxants (tizanidine) as adjunctive therapy if muscle spasm is prominent 4
- Never prescribe opioids for myofascial pain syndrome due to lack of evidence and significant harm potential 1, 2, 5
Manual Therapy
- Apply thermotherapy using microwave diathermy or heat modalities to reduce muscle tension 3
- Incorporate deep tissue massage, myofascial release, or spray-and-stretch techniques as adjunctive treatments 7
Second-Line Interventions (After 4-6 Weeks of Failed Conservative Care)
Advanced Physical Modalities
- Consider high-energy extracorporeal shock wave therapy (0.210 mJ/mm², 1500 pulses weekly for 2 weeks) if conservative treatment fails after 3-6 months, as this demonstrates superior functional improvement compared to low-energy protocols 5, 8
- Transfer energy capacitive and resistive (TECAR) therapy in capacitive mode, 2 sessions weekly for 3 weeks, may provide additional benefit when combined with exercise and medication 4
- Low-level laser therapy, transcutaneous electrical nerve stimulation, and ultrasound therapy have some supporting evidence but remain less established 9, 7
Interventional Procedures to Avoid
- Do not perform trigger point injections with local anesthetic or steroids, as current high-quality guidelines recommend against these procedures for chronic spine pain 1
- Botulinum toxin injections show insufficient evidence for upper back myofascial pain syndrome and should not be routinely used 10, 11, 9
- Dry needling and acupuncture have limited evidence and should be considered only after exhausting proven conservative measures 9, 7
Treatment Duration and Monitoring
- Implement initial conservative treatment for 6-12 weeks before considering alternative interventions 6
- Expect 67-78% of patients to report improvement with appropriate conservative management 3
- Monitor for psychological factors including depression, anxiety, catastrophizing, and fear-avoidance behaviors, as these predict poor outcomes 6
Critical Pitfalls to Avoid
- Do not rely on interventional procedures (trigger point injections, nerve blocks, radiofrequency ablation) as these carry small risks of serious harm including infection, altered consciousness, paralysis, and death, while lacking robust evidence for benefit 1
- Avoid prolonged NSAID use beyond brief initial trials due to cardiovascular and gastrointestinal complications 2
- Do not ignore coexisting conditions such as fibromyalgia, which commonly overlaps with myofascial pain syndrome and complicates assessment 2, 7
- Ensure red flag symptoms (fever, unexplained weight loss, night pain, neurological deficits) are absent before proceeding with conservative management 6, 5
