I found this on my son’s scalp. I have no idea what it is and we can’t get a doctor’s appointment right now. Do you have any advice?

It can be alarming to discover a lump or unusual lesion on your child’s scalp, especially when it’s not possible to see a doctor right away. While a professional examination is always best, some basic knowledge of common scalp problems can help you manage symptoms at home and determine when a doctor’s consultation is necessary.
