hi thanks fr your query your son toppled from the car twice and was cleared from the doctor in the hospital, so dre it ends...plz don t worry and donot relate this to any incidents occurring in the future 1. urine is dark brown in colour,may be related to kidney problems,so you need to get his basic urine routine ,microscopy with albumin ,followed by culture if urine routine turns positive 2. check his blood pressure at regular intervals 3) ASO titres , throat swab for group A streptococcus 4) C3 levels which will be lower than normal 5) treatment is usually supportive and symptoms resolve soon. see a pediatrician with the above reports at the earliest and go for regular follow up regards Dr sowmya
