pain
Start with the big picture
Pain classification helps guide whether treatment should focus on tissue injury, nerve dysfunction, or both. The WHO analgesic ladder offers a framework for stepwise escalation, while medication selection requires attention to safety, monitoring, and patient-specific risks. The lesson reviews acetaminophen, NSAIDs, COX-2 inhibitors, and opioids, including opioid initiation, adverse effects, and overdose-risk mitigation. It also introduces first-line medication groups for neuropathic pain and topical options for localized relief. Special sections address migraine therapies, spasticity-related pain, acute inflammatory flares, multimodal analgesia, and patient-controlled analgesia. These are introductory concepts; individual treatment decisions require clinical judgment and consideration of the patient’s circumstances.
