On the part of the label where it lists the active ingredients in Advil, it says "Ibuprofen". And it says that ibuprofen is a "non-steroidal anti-inflammatory drug." This makes me think that ibuprofen reduces pain by reducing/preventing inflammation (swelling) somehow. I can see how that would work for a muscular ache. One time someone punched me in the back, and it did not hurt right when they punched me. But a few hours later I was in agony. This made me think that it wasn't the force of the blow per se that caused my pain. It was the swelling as a result of the blow that caused me pain. The swelling was caused by white blood cells rushing to the area to repair the damage. Is my supposition that Advil works by reducing/preventing swelling correct? Would Advil reduce the pain from a cut? Say if someone cut their finger accidentally on a saw, would advil reduce the pain from the cut?
