I have had an abscess that is not responding to antibiotics. I am from the UK my surgeon is based in the USA. I have had treatment on the NHS - admitted with a frank abscess in my right nostril, a swab was taken and it was MRSA clear. I had antibiotics intravenously for 3 days and 2 weeks of antibiotics. Another culture was then taken and and showed mixed flora. Another month of antibiotics. My USA surgeon is referring me to a surgeon in the UK. Should I get a further culture testing privately?
