text: is the medical cream, flexall by chattem, the  most powerful sports pain relief cream, for lower back pain ? i cannot take anything like aleve or ibuprofen, the tablets are harmful and too strong for my stomach. my only option is to find a good sports cream. thanks for trying to help... myoflex, blue goo, are both more powerful, but if you are also looking for something that doesn't smell like medicine you should try arnica.  arnica could be found at specialty health food stores and is great for not making your clothes smell.  i know some tennis professionals use it, so that is why i am recommending it to you.
