Scalp bumps on the back of the head can have a long treatment history behind them. Before meeting Dr. U, John says he received a steroid injection directly into the bump, tried different medications, and returned for injections about once a month. After roughly four months, he felt like the bump either got worse or nothing changed. Eventually, he stopped going and spent about two years without seeing a doctor. John’s diagnoses include Acne keloidalis nuchae (AKN), Dissecting cellulitis of the scalp, and Cutis verticis gyrata (CVG). For people searching “what is this bump on the back of my head” or trying to understand painful scalp bumps, John’s story shows why the full medical and treatment history matters. This is one patient’s experience. Treatment should be individualized. What stood out more: the repeated injections or the two-year gap in care? Agree/Disagree: previous treatment history should be part of every new evaluation. Subscribe for the next chapter. #AKN #ScalpBumps #DrSanusiUmar #Baldcast
