@_Whitetigress It’s probably the antiinflammatory properties of the ibuprofen that makes you feel better in general. Not just getting rid of your headache, but also affecting your whole body. Also, pain makes us feel bad in more than one way, it’s a trauma to the body, so relieving the pain stops other bad things that are happening
Ibuprofen is a Cox 1 inhibitor, which is an enzyme in the body. (It might also work on Cox 2 I am not sure? Drugs like prescription Vioxx were promoted as Cox 2 inhibitors, but had serious side effects and was removed from the market. Ibuprofen, although it can have serious side effects, they are fairly rare and the drug has been considered relatively safe for many years). Tylenol inhibits the nerve messages.
