I use Bayer Back & Body every day at work. It is the ONLY thing I can take (without upsetting my stomach) to alleviate the pain in my feet / legs, which I am on for several hours at a time. Bayer Back & Body is very gentle on the stomach and it even has some caffeine in it, which means it can also help with headaches at the same time. In the past, I have had to choose which pain to treat when I also had a headache. But Bayer Back & Body seems to treat any and all pain I normally have, even if I only take a half dose. I have yet to find a better product for work pain, and I have tried them all!
