Do pain killers go exactly where the pain is and just tackle the pain?

Pain killers go into your blood; your blood goes everywhere. Novocain is injected into the pain site (or what will be the pain site) when the Dentist gets ready to drill out your cavity.

The dentist usually injects the Novocain near the nerve bundle near the jaw hinge, where they all come together. That way he gets a whole quadrant’s worth of nerves in one shot.

Edited to add:
Yes, when it comes to dentistry, for frezzing purposes, but if you have pain in different locations the pain killer just tackles the pain areas only, and not do numb the rest of the body. I’m asking this in relation to hand sanitizers kill the bad and the good bacteria OP. If pain killer goes and tackels the pain only then why not some product that will only kill the bad bacteria?

There is only bacteria not good or bad.

Painkillers “knock you out” “don’t drive a car or operate equipment” not only the pain area will stop hurting.

Morphine and Heroin are painkillers don’t operate equipment.

If you take a pain killer orally, like a pill or liquid, then it goes into your blood stream and goes everywhere, not just the place where the pain is. Same if you get the medicine IV, or if it’s a pain patch that delivers medicine.

Pain medicine can work in different ways. It can reduce the transmission of pain so that your brain does not get the signal of pain. Some pain meds reduce inflammation or relax muscles, which can help with certain types of pain.

You don’t “feel” the drug working in other parts of your body, because other parts aren’t in pain. Although, some very strong drugs you will feel all over. For instance, strong muscle relaxers will make you feel more more relaxed all over, and reduce the pain in the area that had been in pain.

Ok, but pain killers don’t destruct, do damage to the areas of the body where there is no pain, whereas hand sanitizers (is it all?) and other things do kill the good bacteria.

You are comparing apples and oranges. As said above, pain relievers relieve pain.
Hand sanitizers kill bacteria.
There is no comparison.

Pain killers don’t destruct anything per se. It’s a temporary reliever of the pain messages being transmitted. Or, if the also work in inflammation or muscle relaxation they actually can be curative, in that over the time the inflammation or muscle cramp will go away long term.

The pain killer isn’t killing the pain or destructing the pain. When you kill bacteria it’s something that was living, and now is dead. When you “kill” or “deaden” pain, you aren’t actually killing something that used to be alive.

They simply make you think it doesn’t hurt. Again, this is a subject very easy to research on a search engine.

I believe they block the nerve receptors in your brain that makes you experience the pain. They don’t block nerve receptors that are experiencing touch or sound or taste.

No.

The point is:
considering landing on the moon, and all the other head spinning things that have been acomplished… no one can say it’s an impossible thing to make the product/s kill just the bad bacteria

Yes you can say “it is impossible” @flo antibiotics are broad spectrum; maybe you should have gotten a PhD in Biochemistry or Pharmacology. The fact that we landed on the Moon has nothing to do with bacteria in your body or on your hands

I have a funny little picture in my mind of line-ups with the “bad bacteria” being picked out and slinking away.

It like starting a fire and you only want to burn red and blue colored paper not green and yellow.

Fire burns everything.

Hopefully, in the future, we will be able to target just the bad bacteria.

Thing is, sometimes we don’t know exactly what bacteria we are fighting, and so broad spectrum drugs are given hoping to kill a lot of different bacterias.

It will be nice when medicine makes some big strides regarding infectious disease. We still have a long way to go, even though things like the discovery of penicillin is nothing short of miraculous, and life giving.

To engineer an antibiotic so that it targets a specific bacteria out of the millions, would make such an antibiotic far, far to expensive to be feasible. And then it may well mutate to become immune to that antibiotic, then you’re back at square one.

That is another reason you can’t compare machines to living things.

If it is injected then yes.

If it’s injected it targets specific bacteria? That makes NO sense @24bedoo. It may be a more powerful antibiotic than what you take orally, but that’s going to be the only difference.

^I think she is talking about pain killers as that was part of the question too.

Oh. Thanks @chyna. I’m getting @flo‘s questions confused! Sorry @24bedoo.

I stand corrected by @janbb
”...they block the nerve receptors in your brain that makes you experience the pain. They don’t block nerve receptors that are experiencing touch or sound or taste.” Bingo. That makes my point perfectly.

Before every invention, a lot of people are naysayers, unlike people who think like: “Hopefully, in the future, we will be able to target just the bad bacteria.”

How does that make your point? She just said what everyone else is saying, “No it doesn’t block specific pain in specific parts of your body.”

….Is it miraculous or what that they just block the pain nerve receptors and not the other nerve receptors?. Beyond beyond.

Of course they do. Right to your head.

They block all the pain receptors @flo. You just don’t notice it unless another part of your body is in pain.
