Hi - a couple of days ago, i felt a nodule right at the top of my rib cage, a little lower than my breast area. there was redness - like a bulls eye, but no tic and the area below the skin feels like a hard nodule. someone suggested cellulitis rednesshard nodule?

Need to examine: It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It could be infection of a hair follicle, folliculitis. Try warm compresses. Do not try to pop it. If it bursts open, apply triple antibiotic cream, available over the counter. If it does not resolve in a week or so, or you get fever, or other nodules appear, see a doctor.
