### Human:\nwhat happens if the pus from an abscess reaches the bloodstream? . i had an abscess in my right axilla. it was drained surgically because of how painful and big it was. i suddenly developed an unexplained rash in my arm. could this be from the drainage in the abscess?\n\n### Assistant: i don't know. i can't examine you but based on the limited information that you shared you need to remain on those antibiotics that i assume your medical provider gave you. a rash on the arm does not imply the infection is in your bloodstream (septicemia). septicemia causes high fever lethargy and you are very very ill.
