Recently, my wife and I went out on a very long walk (over two hours). This may have been a mistake. When we got home and I examined her feet, I notice a small crack with some minor buising on her heel. Unfortunately, where we live, you have to do a lot of up and downs because of the high sidewalks. This was a few days ago and it hasn’t gotten any worse and it may seems to be getting better. However, we don’t want to take any chances. My wife doesn’t like to go to the hospital for minor things (she really doesn’t like hospitals) so she is simply resting her foot (and walking less) and keeping her heel clean. However, is there anything else she should be doing? Any advice given is greatly appreciated.
