What is the difference between muscle relaxants and pain killers?

Muscle relaxants and pain killers serve different purposes in managing discomfort. Muscle relaxants target specific muscle groups to reduce tension and spasms, often used for conditions like Back pain or muscle injuries. Pain killers, or analgesics, alleviate pain more broadly by acting on the nervous system or the site of pain, with common types including nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids. While both can be used together for comprehensive pain management, they have distinct mechanisms of action and effects.
