I have an ingrown toe nail, my pedicurist told me to leave it without cutting for a year or so & it will correct itself. is that true?

Whaaaaa?: Send back to pedicurist school, nail would only be about, oh, 5' long, hope you like open-toed shoes. Do need to let it grow out, so end of nail makes it to end of toe (& can't 'dive' into skin. Then be careful to get all of nail when cut it in future & try to keep it pretty straight across for several months. If continues to be problem, may need to see your dr or a podiatrist for help with it.
