Was told dd has impetigo on wednesday and given antibiotic cream. Last blister appeared on Thursday, by Friday she had no blisters but also no improvement seen in her skin. Went back to docs on Friday and told she fine just keep on with the cream. DD looked much better Saturday but this afternoon 2 new blisters have appeared. Does this mean the cream is not working? She has missed 3 days of school and was hoping she would be back tomorrow. If the new blisters after 4 full days of cream are appearing again does this mean she needs oral antibiotics? Thanks.
