question: Hi my 2 year old ran into the corner of a drawer this evening at 6pm he immediately (within seconds) had a large lump (size of peach stone). I put a cold ice compress on and he seemed fine after a few minutes. The swelling was down (not completely) by his bedtime at 7pm. Should I be looking for any signs of concussion over next day or so? Lump is at front, on the bony part above his left eye.
