Knots. I really don't get this one... Sure, with shoe or pants issues, I have the better tape and the safety pins and the replacement clothes if they need that. But knots? Didn't receive any special training on knots in nursing school...
That seems odd to me. I will recommend a visit to Dr if the rash is on their face or is getting worse, but other than that, they'll be fine. I wonder if she does think it's contagious...
My families have had a lot of success with the prescriptions Natroba and Sklice. They actually do kill the eggs (unlike some of the OTCs that say they do but don't) and are super easy to use and are usually covered by insurance or Medicaid.
