question: I found a pretty sizable squishy spot (about 4" wide) on the side of my 1 year old's head last night (Saturday.) It doesn't seem to hurt him. He did fall on Thursday, but didn't seem too bothered by it and settled down in 20-30 seconds. He has no abnormal symptoms or behaviors. We took him to the ER last night and they suggested a cat scan. With the increase cancer risk from ct scans, we declined it. We will see our pediatrician tomorrow (Monday.) Could this be completely unrelated to a fall? How concerned should I be?
