Since August last year i have been suffering from pustules on my scalp, chest and face. i had heavy dandruff as well. I went to the doctor in September and upon pus culture found Staph bacteria. I was advised antibiotics, soap, shampoo etc. It went down. There was another outbreak in Jan and underwent a similar course again. Now i had a very heavy re-occurence with thick pustules in groups over scalp and chest and pustules on face. I went for a pus culture and E Coli was diagnosed. I don't know what is happening. I have an acne history and had gone for isotretinon treatment and some oral antibiotic creams. This is not just painful but also scary. Please suggest
