 Dr. Gregg, how about knowing what to do? How do I recognize that I have hurt my foot, that I need to come see you? What are some of the most common things that bring folks to Central Minnesota foot and ankle when it comes to an injury? Certainly with an injury, if it's something that you're noticing bruising or significant swelling or it's difficult to walk on, you should have that looked at as soon as possible. If it's something that's been nagging otherwise for more than a few days or a week, it's also probably a good idea to start to come in and have it looked at.
