I have really painful bursitis in my shoulder. I have tried many over the counter pain relievers but they do nothing for the pain. I recently tried the Myoflew maximum strength pain rub and love it. It takes away the pain. It even works for my 10 yr old who has a metal plate in her leg she also gets a lot of pain. I like that it works for her she is to young to be taking pain meds. This is a great product. I truly recommend it to those that have muscle or joint pain that doesn't get any relief with pain pills.
