Never had it. The dr. I work for says shots for only the worst cases, steroids. All the above remedies work just have to find out what works for him. Need to wash everything even his shoes. That oil can remain active for a year or so if he touches his shoes again. If you had a dog with you, could have it on his coat. It's amazing how that stuff spreads. His eyes, poor thing. Bumps run in lines. Hope the dr. helps soon.
