<s>[INST] My 2year old son has a small bump on in head.As far as we remember he never fell hard on his head except once about 10months ago.He then just cried for a little while and was quite normal.He didnt lose conciousness or vomit.But now if we run a hand on his head we can feel the bump as a soft lump.Just today I got the xray done and on the xray I could see a clear crack running from top to the forehead.The radiologists said it is the joint and the doctor would tell if it is in the right position for a 2year old.The reports would be sent back to the doctor in two days.I am too worried to wait for that long so was surfing on the web to see similar articles.Can someone help me with that please?What might be the adverse effects if it is a fracture?
