[|Human|] My baby is 5 months old. I noticed today he has a bumpy lump under skin on his head. I wonder is that something I should be concerned about?I carefully handle him. Do not remember that he hit his head against something. It is maybe few millimeters long, something like a piece of pea.
[|AI|]  Hi, Thanks and welcome to Chat Doctor. A minor injury over head leading to small bump is negligible if the baby is normal. But it is wise to observe for lethargy, vomiting and fits for 48 hours to rule out head injury. No worry if the baby normal for 48 hours. If any of the above symptoms appear take him to ER. Hope this reply is OK for you. Please feel free to ask further queries if any. Chat Doctor. V. Subrahmanyam.
