It's unclear what this product is supposed to do. I've been dealing with a really sore upper back with the pain concentrated at one point. I asked the customer service representative online as well as in the store how to choose between the Arnica and Recovery and their response was to ask me what my problem was and just recommend Recovery. My guess is they don't know either what the product does. I've been using it for a week now with no results. How does one formulation address skin as well as muscle issues?
