[|Human|] My son is almost 8 months. He fell off the bed a little over a week ago.We were not sure if he hit his head. We took him to the ER and everything checked out ok. No marks or bumps on his head or anywhere else. 6 days later he has a big, soft, squishy lump on the right side of his head. He is acting normal. Took him to the pediatrician yesterday and they sent us for a cat scan. They said everything looks fine and it s probably swelling from when he fell. And it could be there for another week or so. But, it s doesn t seem to be going down and Ifeel like it may vbe getting harder. Why would this lump take so long to show up if he in deed hit his head? Could it be something else? Should I get another opinion?
[|AI|]  HI...coming to your queries.1. Usually a soft tissue swelling like this will take sometimes 2-3 weeks also to go off completely.2. The other possibility is a hematoma or a subcutaneous blood collection, and it is also harmless and take almost the same time to resolve.3. You need not get another opinion. . First be reassured that your kid is normal. I will suggest you danger signs of head injury -1. Vomiting continuously2. Seizures3. Watery of bloody discharge from ears and nose4. Unconsciousness5. Altered sensorial or behavior. If none of them are present, I don't think you should worry about his trivial head injury. Regards -
