<s>[INST] My son fell from a 3 foot drop right on the back of his head on ceramic tile, 3 days later i noticed a soft spot, hes been acting normal and that spot is still there. If i touch the spot he moves and whines. im just worried, we took him to the hospital and the doctor said it was a cyst. but i dont think so, and the pediatrician said it was no cysts and that it was from the fall i am very worried. [/INST] Hi...it is just a boggy swelling what you are describing. It occurs because of the trivial injury he had during the fall. Nothing to worry. It will get absorbed by itself in matter to 7-10 days. It is definitely not a cyst. At this point I will suggest you the danger signs when you need to worry after a head injury. Be rest assured. Danger signs of head injury include -1. Vomiting continuously2. Seizures3. Watery of bloody discharge from ears and nose4. Unconsciousness5. Altered sensorial or behavior. Regards -  </s>
