endorphins are painkillers that are naturally produced by the body, whereas opioids are painkillers that are found or synthesized outside the body.
Painkillers and NSAIDs are analgesics, which are medications used to treat pain. The most significant distinction is that painkillers target the level of pain you're experiencing by stopping pain signals before they reach the brain.
NSAIDs, commonly known as nonsteroidal anti-inflammatory medicines, serve to reduce pain and fever by lowering inflammation.
However, if you have chronic pain or inflammation, they are unlikely to alleviate the underlying cause.
