Jane, regarding your foot. I'm a big fan of Arnica. The Arnica Rub is my favorite of the Arnica topicals, since it has lots of other remedies in it as well. About a week ago I started a little trial of Topricin, a homeopathic cream for arthritis. I'm using it on my two arthritic fingers. It's helping. If you don't get results with Arnica, you may want to try Topricin. I've seen in on Amazon. It's very easy to use--no smell, absorbs easily, etc.
