Suggest Treatment For Boils And Carbuncles On The Back And Buttocks

Hi, may I answer your health queries right now ? Please type your query here... I am 66yrs, female, with marfan syndrome. I have a ascending,decending and abdominal aortic graft, COPD, artifical heart value, and suffer from congestive heart failure. During my recent surgery to replace and repair another aneyrysm my spleen was removed. Now I have developed a severe skin condition- boils with pus and carbucles (multiple boils) on my back and buttocks. I am concerned that I need an antibiotic. Do I?
