The recovery period for a minor brain hemorrhage after a car accident is about 3 months. It is important to get through the 2 most dangerous periods before gradually stabilizing to reach the recovery period. 1. The most dramatic and unstable period is within 3 days after the brain hemorrhage, during which it is most feared that poor blood pressure control or poor coagulation mechanisms in the body may lead to rebleeding or increased bleeding. This can be very damaging to the patient and sometimes even requires surgery.2. 10-14 days after a brain hemorrhage is the peak period of brain swelling. Only by spending the above 2 periods can the later recovery be relatively smooth. Problems in any 1 of the 2 periods can cause adverse reactions and more serious complications, so the recovery period for minor brain hemorrhage after a car accident is around 3 months.
