Dear Danielle I am sorry to hear that you have got impetgo. This is usually caused by bacteria staph Aurius, very ocationally strep Pyogenis. I am sure your Doctor has given you appropriate antibiotic and the condition will start to settle down within 48 hours.It is recomended to apply antibiotic cream over the lesion. If you notice enlarged lymph
glands in the neck, get high fever
or detoriation of your condition you must see your doctor to review the situation sending swabs from the lesions, if necessary to send blood for culture. I hope you should get speedy recovery. Kindest regards.
