I saw that just this morning also. She must have been in some kind of pain for some time to keep using it over and over. I have used Ben-Gay in the past to run on the back of my legs when I have overdone it, but now I just use Biofreese. It comes in a spray, roll-on, and gel. I use the spray on my toes if they are acting up. I can't say this is a great solution, but sure does help for a while. I use the roll-on on the bottom of my feet when they are just sore from being on my feet for too long. These two are nice in that you don't get your hands all messy!
