Dear all, i am not sure where this should go but.... I was wondering how pain killers know where the pain is in your body.. Do they have some sort of a radar thing which homes in on the pain or are they just generic as in they work through out the body and hope to hit the pain bits? Also this applies to Antibiotics and stuff, and probably most medicine which is not injected into the specific area of the body it is meant to be working on. ~~~~~~~~~~ take it ez zak
From my mediocre knowledge, pain is blocked by interfering with the receptor chemicals. In order for you to sense pain, a signal has to be sent from one nerve cell to the other, and eventually to the brain. Blocking these prevents pain, so typically it is a system wide effect. http://www.webmd.com/pain-management/advanced-reading-understanding-pain explains better than I. Blocking these signals, though, is the way to fight pain.
