Dermatology Questions? Ask an Online Dermatologist.
Hi--can you tell me more about this please?
OK. If it were a bite that sounds like one from a brown recluse spider but it could be either a hair shaft infection or an area of cellulitis
Since there's pus there, even if it were an insect bite it now is definitely infected and it could be MRSA. At this point she needs a course of antibiotics so she should see a doctor about this.
Let me know if you need any more information please
My pleasure but please remember to rate my service to you
