Speed, science and optimal pain relief [PDF]

International Journal of Clinical Practice, 2015
Pain is a major global health problem. Six of the 11 most prevalent conditions worldwide are pain-related, with tension-type headache and migraine being the second and third most prevalent conditions. Pain also ranks high among the conditions that have the longest-lasting impact: five of the top 11 contributors to years lived with disability are pain ...
