Aww... I hope this heals quickly. My oldest DD has had this problem several times and twice had the toenail removed. Soaking it in Epsom Salt and warm water helps to break that up and allows the medication to work. Since the last time, we learned why... she was wearing shoes which were too small for her. My mom was really bad about this because my DD loved to play with her shoes, or they would find a pair she like and get the smaller size if they didn't have her size. I'm religious about making sure she has the correct size shoe now and not allowing her to play in shoes too small for her. My mom now has a couple of dress-up shoes in her size for her to play in.
