<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 HCM.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 drug like benadryl . Apply broad spectrum sunscreen such as TANCARE to face all the times to prevent your sking from direct sunlight . Apply vitamin C serum at night. If condition doesn't improve in a week then consult dermatologist for proper examination . Doctor may prescribe steroid ointment and retinoids .Hope your concern has been resolved.Get Well Soon.Best Wishes,Dr. Harry Maheshwari </s>
