TED-Ed: How do pain relievers work? - George Zaidan

The video explains the role of pain as a protective mechanism, highlighting nociceptors as specialized nerve cells that detect potential harm. It discusses how pain thresholds can be altered by chemicals and how common painkillers like aspirin and ibuprofen work by blocking enzymes that produce pain-inducing chemicals. The video also touches on neuropathic pain and the brain's influence on pain perception, emphasizing ongoing research in pain management.
