10 Symptoms of Staph Infection

4. Blisters and Sores

If you notice small red blisters around your mouth and nose that are itchy but not painful, you may be suffering from non-bullous impetigo, the most common form of impetigo. After a few days, these blisters will burst and develop a brownish-yellow crust, but the crust will heal with minimal to no scarring. If you find that you’re developing larger blisters that are more painful, you may have bullous impetigo (though this usually occurs in small children). These blisters will also form a yellowish crust after bursting but generally heal without scarring. Both of these types of impetigo are caused by a staph infection and can be treated with topical antibiotics. Because impetigo is highly contagious, it’s important to see your physician right away to begin treatment.
