my daughter scraped the complete top of her knee last week. I have been cleansing it with normal saline, and dressing it with solusite, lyofoam, and a clear plastic dressing. The last two days I have covered it with the solusite, lyofoam, and fixamol (as this breathes). She has developed red, itchy pimply type rash which is extending down from the knee. This is getting worse and the spots getting bigger. Just wondering if it may be fungal, or what it could be? thanks for your help
