I’ve been told before that opiates aren’t useful for chronic pain, but I always assumed that was due to the risk of addiction. I had major surgery recently and was on morphine in the hospital and Vicodin after leaving. I hardly experienced any pain from the surgical site while on the medications, but my chronic shoulder pain seemed to be unaffected. Can anyone explain why this would be the case?

Chronic pain is often caused by changes in the nervous system, which makes it less responsive to opioid painkillers. While opioids can provide relief for acute pain, they are not as effective for long-term pain management.
