My daughter got sick ангиной, after the disease was heavy, and so he had to drip a lot of antibiotics. After the release of her began to bother pain in the knees. It turns out, osteoarthritis has emerged as a complication after pain in the neck. He didn't want to give the child some more chemical treatment, but, fortunately, he got the explanatory doctor and he suggested to use the cream Motion Free. After the course application daughter runs and jumps with all the kids, and even couldn't sleep because of the pain. Thanks!
