Question

how does pain killer works

Answer 1

When part of your body is injured, special nerve endings send painmessages back to your brain. Painkilling drugs interfere with these messages, either at the site of the injury, in the spinal cord or in the brain itself. Many painkillers are based on one of two naturally occurring drugs: aspirin and opiates.

Answer 2

All painkillers work by interfering with the pain - transmission process. Although there are many different types, painkillers or analgesics - usually relieve in pain.
