my 7 year old fell off my shoulders while at a mardi gras parade and hit head first on street a week ago yesterday. he immediately had a large hematoma pop up. we took him to see the ems at the parade site. I m also a RN. he had no complaints at all then other than it hurt and none since. pupils fine, vision fine, no headaches, dizziness , no nausea/ vomiting , nothing at all. the area is on his forehead right above his left brow. I just noticed tonight that there is a hard knot still there. the discoloration is all gone. wondering if I need to take him in or not?
