Question: Thank you! I have a young friend (female, age 14) that has something on her right wrist on the inside that started about a wk ago as a rash or something that thought was maybe a spider bite. The dr. said it might be shingles, but it was only in that spot and no pain, itching, etc.

It is no awful looking with skin peeling, spreading in the same area & a huge blister with other smaller ones in the same area. I do have a photo of it today.

Any ideas?

Brief Answer:

Bullous Impetigo

Detailed Answer:


I have noted your concern and I have viewed the images.
Seems like bullous Impetigo - a bacterial skin infection.

I suggest an oral antibiotic e.g either Amoxicillin or Cephalexin, thrice daily for a week.

Topically she may use an antibacterial ointment e.g either Neosporin ointment or Mupirocin 2 %ointment, twice daily.

Hope I have answered your query.

Take care
