 Wearing closed-toe shoes does not mean the foot problems go away. Hi, I'm Dr. Karen Rao with Central Minnesota Foot and Ankle. Ingrown toenails, athlete's foot, toenail fungus, and corns are all very common foot problems. If you ignore them, they do not go away. If you wait too long, your treatment options may be more severe. Many of these foot problems can be cured with at-home remedies. Both myself and Dr. Greg Rao are board-certified podiatrists, true specialists of the foot and ankle.
