Acetaminophen is currently under investigation, it's not exactly good for you

I stopped taking IBuprofen because it hurt my stomach... but it was the only thing that worked OTC for inflammation in my back, arm, wrist, etc... I got prescribed diclofenc (I believe) which is a once a day if I remember and is not supposed to be so bad but it also isn't as good it seems.

Most chemicals it seems are evil
