*Pain is the chief complaint in up to 70% of all ED visits&amp;lt;ref name=&amp;quot;motov&amp;quot;&amp;gt;Motov S, Strayer R, Hayes BD, et al. Pain management in the emergency department: a clinical review. ''Clin Exp Emerg Med''. 2022;9(2):118-132.&amp;lt;/ref&amp;gt;&lt;br /&gt;
*Subacute pain (1-3 months) represents a critical window for prevention of chronification&lt;br /&gt;
*Emergency physicians are not the primary drivers of chronic opioid prescriptions, but ED visits represent an important touchpoint for intervention&amp;lt;ref name=&amp;quot;acep2020&amp;quot;&amp;gt;Hatten BW, Cantrill SV, Dubin JS, et al. Clinical Policy: Critical Issues Related to Opioids in Adult Patients Presenting to the Emergency Department. ''Ann Emerg Med''. 2020;76(3):e13-e39.&amp;lt;/ref&amp;gt;&lt;br /&gt;
*1-5% of opioid-naive patients prescribed opioids in the ED may develop prolonged use&amp;lt;ref name=&amp;quot;acep2020&amp;quot;/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Classification==&lt;br /&gt;
*'''Nociceptive''' — activation of peripheral pain receptors; somatic (MSK, cutaneous) or visceral&lt;br /&gt;
*'''Neuropathic''' — damage or dysfunction of the somatosensory nervous system (e.g., [[diabetic neuropathy]], [[post-herpetic neuralgia]], [[complex regional pain syndrome]])&lt;br /&gt;
*'''Nociplastic''' — altered nociceptive processing without clear tissue or nerve damage (e.g., [[fibromyalgia]], [[irritable bowel syndrome]], chronic primary pain)&lt;br /&gt;
*'''Mixed''' — most common in practice; often has nociceptive + neuropathic + central sensitization components&lt;br /&gt;
&lt;br /&gt;
==Common Chronic Pain Presentations==&lt;br /&gt;
*'''[[Low back pain]]''' — most common chronic pain complaint in the ED&lt;br /&gt;
*'''[[Headache]] / [[Migraine]]'''&lt;br /&gt;
*'''Abdominal/pelvic pain''' — chronic abdominal pain, [[endometriosis]], [[irritable bowel syndrome]]&lt;br /&gt;
*'''MSK pain''' — [[osteoarthritis]], [[fibromyalgia]], myofascial pain&lt;br /&gt;
*'''Neuropathic pain''' — [[diabetic neuropathy]], [[complex regional pain syndrome]], radiculopathy&lt;br /&gt;
*'''[[Sickle cell disease]] pain crises''' (managed per separate disease-specific protocols; excluded from CDC opioid guidelines)&lt;br /&gt;
*'''Cancer-related pain''' (excluded from CDC opioid guidelines; treat aggressively)&lt;br /&gt;
&lt;br /&gt;
==Evaluation==&lt;br /&gt;
*'''Rule out dangerous etiologies''' masquerading as chronic pain exacerbations (the primary role of the EP)&lt;br /&gt;
*Identify new or worsening pathology requiring urgent intervention&lt;br /&gt;
*Assess functional status and current treatment regimen&lt;br /&gt;
*Screen for opioid use disorder and substance misuse&lt;br /&gt;
&lt;br /&gt;
===History===&lt;br /&gt;
*Onset, character, location, radiation, severity, aggravating/alleviating factors&lt;br /&gt;
*Prior workup and diagnoses&lt;br /&gt;
*Current pain management regimen — ask specifically about:&lt;br /&gt;
**Prescribed medications (opioids, gabapentinoids, muscle relaxants, antidepressants)&lt;br /&gt;
**OTC medications ([[acetaminophen]], [[NSAIDs]])&lt;br /&gt;
**Non-prescribed substances (kratom, [[tianeptine]], cannabis, illicit opioids)&lt;br /&gt;
**Non-pharmacologic treatments (PT, injections, neurostimulation)&lt;br /&gt;
*Functional impact: work, sleep, ADLs&lt;br /&gt;
*History of substance use disorder&lt;br /&gt;
*Who manages their pain (PCP, pain specialist)&lt;br /&gt;
&lt;br /&gt;
===Red Flags===&lt;br /&gt;
*'''[[Cauda equina syndrome]]''' — bilateral leg weakness, saddle anesthesia, bowel/bladder dysfunction&lt;br /&gt;
*'''[[Epidural abscess]] / [[spinal epidural abscess]]''' — fever + back pain + neurologic deficit (especially in IVDU or immunocompromised)&lt;br /&gt;
*'''Malignancy''' — new or worsening pain in cancer patients, unexplained weight loss, night sweats&lt;br /&gt;
*'''[[Aortic dissection]] / [[AAA]]''' — new tearing chest/back/abdominal pain&lt;br /&gt;
*'''Fracture''' — new pain after trauma, especially in osteoporotic patients&lt;br /&gt;
*'''[[Necrotizing fasciitis]]''' — pain out of proportion with skin findings, rapidly progressing&lt;br /&gt;
*'''Visceral emergency''' — [[bowel obstruction]], [[ovarian torsion]], [[ectopic pregnancy]], [[appendicitis]]&lt;br /&gt;
&lt;br /&gt;
===Workup===&lt;br /&gt;
*Imaging and labs should be guided by clinical concern for acute pathology, NOT routinely obtained for chronic pain exacerbations&lt;br /&gt;
*Check PDMP (Prescription Drug Monitoring Program) — recommended before prescribing opioids&amp;lt;ref name=&amp;quot;cdc2022&amp;quot;/&amp;gt;&lt;br /&gt;
*Consider [[EKG]] if on QT-prolonging medications ([[methadone]], certain antidepressants)&lt;br /&gt;
&lt;br /&gt;
==Management==&lt;br /&gt;
*Set realistic expectations — the goal is improved function and symptom management, not elimination of pain&lt;br /&gt;
*Use multimodal analgesia whenever possible&lt;br /&gt;
*Non-opioid therapies are preferred for chronic pain exacerbations in the ED&amp;lt;ref name=&amp;quot;acep2020&amp;quot;/&amp;gt;&lt;br /&gt;
*'''Do not routinely prescribe opioids to treat an acute exacerbation of non-cancer chronic pain''' for patients discharged from the ED (ACEP Level C recommendation)&amp;lt;ref name=&amp;quot;acep2020&amp;quot;/&amp;gt;&lt;br /&gt;
*Do not abruptly discontinue or taper a patient's home chronic opioid regimen from the ED&lt;br /&gt;
*'''Do not co-prescribe opioids + benzodiazepines''' for pain (ACEP consensus recommendation)&amp;lt;ref name=&amp;quot;acep2020&amp;quot;/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Non-Pharmacologic Therapies===&lt;br /&gt;
*Heat/ice application&lt;br /&gt;
*Positioning and splinting&lt;br /&gt;
*Referral to physical therapy&lt;br /&gt;
*Brief counseling on activity modification and self-management strategies&lt;br /&gt;
&lt;br /&gt;
===Pharmacologic Therapies — Non-Opioid (First Line)===&lt;br /&gt;
&lt;br /&gt;
====Acetaminophen====&lt;br /&gt;
*1000 mg PO/IV q6-8h (max 3-4 g/day; 2 g/day if hepatic impairment or chronic [[alcohol]] use)&lt;br /&gt;
*Safe and effective for many pain types; often underutilized&lt;br /&gt;
*IV formulation available but costly; PO equivalent in efficacy for most indications&lt;br /&gt;
&lt;br /&gt;
====NSAIDs====&lt;br /&gt;
*[[Ibuprofen]] 400-800 mg PO q6-8h&lt;br /&gt;
*[[Ketorolac]] 15-30 mg IV/IM (not to exceed 5 days total course; avoid in renal disease, GI bleed risk, elderly, pregnancy)&lt;br /&gt;
*[[Naproxen]] 250-500 mg PO q12h&lt;br /&gt;
*Avoid in [[CKD]], [[GI bleed]] risk, [[CHF]], third trimester [[pregnancy]]&lt;br /&gt;
*Effective for MSK pain, renal colic, headache&lt;br /&gt;
&lt;br /&gt;
====Ketamine (Subdissociative Dose)====&lt;br /&gt;
*'''IV''': 0.1-0.3 mg/kg over 15 minutes&amp;lt;ref name=&amp;quot;sdk&amp;quot;&amp;gt;Motov S, Drapkin J, Likourezos A, et al. Sub-dissociative dose ketamine administration for managing pain in the emergency department. ''World J Emerg Med''. 2018;9(4):249-255.&amp;lt;/ref&amp;gt;&lt;br /&gt;
**Lower end (0.1 mg/kg) preferred in elderly and obese patients&lt;br /&gt;
**Short infusion over 15 min reduces psychoperceptual side effects vs. IV push&lt;br /&gt;
*'''Intranasal''': 0.5-1 mg/kg via atomizer&lt;br /&gt;
*'''Nebulized''': 0.75 mg/kg via breath-actuated nebulizer&amp;lt;ref name=&amp;quot;nebket&amp;quot;&amp;gt;Nguyen T, Mai M, Choudhary A, et al. Comparison of Nebulized Ketamine to Intravenous Subdissociative Dose Ketamine. ''Ann Emerg Med''. 2024;84(4):354-362.&amp;lt;/ref&amp;gt;&lt;br /&gt;
*Continuous infusion: 0.15-0.2 mg/kg/hr, titrated q30 min&amp;lt;ref name=&amp;quot;sdk&amp;quot;/&amp;gt;&lt;br /&gt;
*Particularly useful in opioid-tolerant patients, central sensitization, and as opioid-sparing adjunct&lt;br /&gt;
*Common side effects: dizziness, nausea, feeling of unreality (transient, typically &amp;lt;30 min)&lt;br /&gt;
*Avoid in patients with active psychosis; safe in controlled [[hypertension]] and elevated [[ICP]] (previously disproven concern)&lt;br /&gt;
*No respiratory monitoring required at subdissociative doses&lt;br /&gt;
&lt;br /&gt;
====Gabapentinoids====&lt;br /&gt;
*Useful for neuropathic pain&lt;br /&gt;
*Generally best initiated by PCP/pain specialist rather than ED&lt;br /&gt;
*Use caution when combined with opioids (risk of respiratory depression)&lt;br /&gt;
&lt;br /&gt;
====Lidocaine====&lt;br /&gt;
*'''IV lidocaine''': 1-1.5 mg/kg over 10-15 min — mixed evidence; may consider for refractory pain&lt;br /&gt;
*Topical lidocaine patches for localized MSK or neuropathic pain&lt;br /&gt;
&lt;br /&gt;
====Muscle Relaxants====&lt;br /&gt;
*[[Cyclobenzaprine]] 5-10 mg PO — for acute MSK spasm&lt;br /&gt;
*[[Methocarbamol]] 750-1500 mg PO — less sedating alternative&lt;br /&gt;
*[[Baclofen]] — avoid initiating from ED (complex dosing, withdrawal risk)&lt;br /&gt;
*Avoid [[carisoprodol]] (high abuse potential)&lt;br /&gt;
*Avoid co-prescribing with opioids or benzodiazepines&lt;br /&gt;
&lt;br /&gt;
====Trigger Point Injections====&lt;br /&gt;
*Effective for myofascial pain with identifiable trigger points&lt;br /&gt;
*Use lidocaine or bupivacaine ± small volume of corticosteroid&lt;br /&gt;
*Can be performed in the ED for low back pain, neck pain, and shoulder girdle pain&lt;br /&gt;
&lt;br /&gt;
===Opioids===&lt;br /&gt;
*Acute exacerbation of cancer-related pain&lt;br /&gt;
*[[Sickle cell]] vaso-occlusive crisis (disease-specific protocols apply)&lt;br /&gt;
*Severe acute-on-chronic pain after non-opioid therapies have been maximized or are contraindicated&lt;br /&gt;
*Short-term bridge while awaiting definitive intervention (e.g., surgical repair)&lt;br /&gt;
*If prescribing opioids&lt;br /&gt;
**Use '''immediate-release''' formulations only (never initiate ER/LA from the ED)&amp;lt;ref name=&amp;quot;cdc2022&amp;quot;/&amp;gt;&lt;br /&gt;
**Prescribe the '''lowest effective dose''' for the '''shortest feasible duration''' (≤3-7 days)&amp;lt;ref name=&amp;quot;cdc2022&amp;quot;/&amp;gt;&lt;br /&gt;
**Check the '''PDMP''' before prescribing&amp;lt;ref name=&amp;quot;cdc2022&amp;quot;/&amp;gt;&lt;br /&gt;
**Avoid co-prescribing with [[benzodiazepines]] or other sedative-hypnotics&amp;lt;ref name=&amp;quot;acep2020&amp;quot;/&amp;gt;&lt;br /&gt;
**Counsel on risks, safe storage, and disposal&lt;br /&gt;
**Consider co-prescribing [[naloxone]] if risk factors for overdose are present&amp;lt;ref name=&amp;quot;cdc2022&amp;quot;/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Special Population: Patients on Buprenorphine/Methadone Maintenance===&lt;br /&gt;
*'''Do NOT discontinue buprenorphine or methadone''' in the setting of acute pain&amp;lt;ref name=&amp;quot;alford&amp;quot;&amp;gt;Alford DP, Compton P, Samet JH. Acute pain management for patients receiving maintenance methadone or buprenorphine therapy. ''Ann Intern Med''. 2006;144(2):127-134.&amp;lt;/ref&amp;gt;&lt;br /&gt;
*The maintenance dose does NOT provide adequate analgesia (analgesic duration 4-8 hours vs. withdrawal suppression 24-48 hours)&amp;lt;ref name=&amp;quot;alford&amp;quot;/&amp;gt;&lt;br /&gt;
*These patients are opioid-tolerant and may require '''higher than typical doses''' of short-acting full-agonist opioids for acute pain&amp;lt;ref name=&amp;quot;alford&amp;quot;/&amp;gt;&lt;br /&gt;
*'''Multimodal analgesia''' is essential: maximize NSAIDs, acetaminophen, ketamine, nerve blocks&lt;br /&gt;
*For patients on '''buprenorphine''':&lt;br /&gt;
**Continue home buprenorphine dose&lt;br /&gt;
**Can administer additional full-agonist opioids on top (buprenorphine's &amp;quot;ceiling effect&amp;quot; is for euphoria/respiratory depression, NOT for blocking analgesia from added full agonists in most clinical scenarios)&lt;br /&gt;
**Consider splitting buprenorphine into q8h dosing for added analgesic benefit&lt;br /&gt;
*For patients on '''methadone''':&lt;br /&gt;
**Verify dose with the methadone clinic&lt;br /&gt;
**Continue home dose; add short-acting opioids PRN for acute pain&lt;br /&gt;
**Think of methadone as &amp;quot;basal insulin&amp;quot; — patients still need &amp;quot;bolus&amp;quot; analgesia for acute pain&lt;br /&gt;
*Consult addiction medicine if available; notify outpatient provider of ED visit and any medication changes&lt;br /&gt;
&lt;br /&gt;
===Special Population: Patients on Naltrexone===&lt;br /&gt;
*Oral naltrexone: effective opioid blockade for 24-72 hours&lt;br /&gt;
*Extended-release injectable naltrexone (Vivitrol): blockade for up to 30 days&lt;br /&gt;
*Opioids will have reduced or absent analgesic effect while naltrexone is active&lt;br /&gt;
*Management strategy: maximize non-opioid multimodal analgesia (ketamine, NSAIDs, nerve blocks, regional anesthesia)&lt;br /&gt;
*For severe pain requiring opioids: may need very high doses to overcome blockade (risk of respiratory depression when blockade wears off — discuss with toxicology/pain)&lt;br /&gt;
&lt;br /&gt;
==Disposition==&lt;br /&gt;
*Most chronic pain exacerbations can be safely discharged with adequate analgesia and follow-up&lt;br /&gt;
*'''Discharge with:'''&lt;br /&gt;
**Appropriate short-term analgesic prescriptions (prefer non-opioids)&lt;br /&gt;
**Clear follow-up plan with PCP or pain specialist (within 1-2 weeks)&lt;br /&gt;
**Patient education on multimodal self-management&lt;br /&gt;
**Naloxone prescription if on chronic opioids or identified risk for overdose&lt;br /&gt;
*'''Admission considerations:'''&lt;br /&gt;
**Acute pathology requiring inpatient workup or intervention&lt;br /&gt;
**Pain crisis refractory to ED management (e.g., severe sickle cell crisis)&lt;br /&gt;
**Concern for inability to manage pain safely at home (e.g., suicidality, severe functional decline)&lt;br /&gt;
**Need for IV analgesic regimen not feasible outpatient&lt;br /&gt;
