There are two main classes of painkiller and they work via different mechanisms. The first class are aspirin drugs, such as paracetamol and ibuprofen. They work chiefly by blocking the body's production of prostaglandins, one of the main sets of chemicals that produce the sensation of swelling and pain. They act at the site of the injury and as the level of prostaglandins is reduced, swelling is reduced and the intensity of the pain is reduced.
The second class of painkillers are the narcotic drugs, such as morphine and codeine. They work by blocking the path of the chemical messengers that signal pain in the spinal cord and brain.

It works the same way as morphine it is an analgesic the drug tells the pain receptors(opiode receptors) or rather the brain tells the drug to flood those receptors with endorphines which blocks the receptors from sending pain signals to the brain. therefore eleviating the pain. Basically the drug just blocks the elecrical impulses that make us feel pain. But as paracetamol is an analgesic it would relieve pain anywhere on your body. E.G cancer patients are given morphine or heroin(diamorphine) because they have pain all over. Paracetamol is not from the opium poppy but it is in the same drug group only much much weaker.

It doesn't - paracetamol blocks pain from the brain.
Ibuprofen goes to the site where pain is - but I don't know how it works.

The active ingredients work on the pain receptors in the brain and fool them into thinking there is no pain. So regardless of where the actual pain site is, your brain's ability to interpret the sensation is blocked or at the very least, reduced.

Some painkillers also contain anti-inflammatory agents, which reduce the swelling and effects of the cause of the pain.

It doesn't. It interupts the signals reaching your brain about the pain, irrespective of where it comes from.

It dosen't
It gets carried around your body in your blood stream and numbs nerves so that stops the pain.
