My daughter got a large abrasion and a few lacerations when she fell rollarblading three days ago.  She had pants on so did not come into contact with the pavement.  The area has been very red and swollen from the abrasion but the lacerations have scabbed over.  they are yellow under the scab though.  Does the yellow color indicate infection?
Hello. Thanks for writing to us at Chat Doctor Swelling, redness and yellow colored base or floor of laceration does indicate that the area is infected. If I was the treating doctor I would have started her on an empirical course of oral antibiotics e.g. either flucloxacillin Or cephalexin, for a week to take care of the infection. Oral antibiotics are prescription products and I would suggest that you talk to your physician for the needful. The wound should be cleaned daily an antiseptic solution e.g. Betadine solution. Topically you may use an OTC topical antibacterial e.g. 2% mupirocin ointment, twice daily, after cleansing. Regars
