Hi Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern... Impetigo is a highly infectious bacterial skin infection caused by bacteria named Staphylococcus aureus. Most common among preschool children. People who play close contact sports, such as rugby, American football, and wrestling or boxing, are also susceptible to this disease. Treatment may involve washing with soap and water and letting the impetigo dry in the air whenever possible. Mild cases may be treated with bactericidal ointment. More severe cases require oral antibiotics, such as dicloxacillin, flucloxacillin, or erythromycin. Alternatively, amoxicillin combined with clavulanate potassium, cephalosporins,etc are given. So you should visit a dermatologist, he would check it and prescribe antibiotics Don t worry you would be fine Hoping your query is solved.
