Hello everyone! Yesterday we had an appointment with the pediatrician and he slightly pulled back the edge of the skin. He didn't open the head. And that same day at night I noticed redness there. Although the whole day was normal. On the very edge of the skin, as if a piece of skin was torn off. Could this be due to the doctor's manipulation? My son has never been to that place before. Now I'm rinsing it with iodine and have already scheduled an appointment with a doctor. Has anyone encountered something similar?
