<s>[INST] Hello, I developed a rash on the left side of the back of my neck on Friday - this ended up raising up into bumps. This has since spread to my ear with white bumps/postules. The back of my neck has gone down after being rubbed with fucidine over the past few days and gone down, but the spots have turned into black scabs. I think my ear is about a day or so behind. Any ideas what this is? [/INST] Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per you query you have symptoms of spreading raised white bumps on neck and ear which is pointing towards a condition known folliculitis due to hair follicle infection, and it could be due to contact dermatitis as well. Sometimes it occurs due to allergic reaction as well or side effects of certain medicine. I would suggest you to wash your face with cold water and apply tea tree oil. Apply cold compresses to your face 2-3 times a day. Take antihistamine Chat Doctor.  </s>
