What are these? Developed first on face then spread to arms. Very itchy
Asking for my friends mom who’s had this since February. She’s been to the er and 2 dermatologists, tried steroids and ointments, nothing seems to be helping. They’re a bit more healed now but still very itchy and painful for her. Located on her right cheek and all down her right arm. What could this be? She just gave birth about 6 months ago if that helps anything.
