Which one is better to use and why? I'm thinking mainly for arthritis, PMS cramps, backaches, headaches, things like that. Ice works well on headaches but not always completely. I can't take much tylenol or anything with it in it because I was put on a medication that affects my liver directly and I haven't gotten liver enzymes done yet to see if it affects it too much. So Tylenol is kind of out for the time being. Any suggestions whether to use motrin or advil and why? Thanks.
