When people are involved in an auto accident, they generally refuse to see a doctor or contact an attorney. This is particularly true for people who are not seriously hurt. They often feel lucky to have walked away, without any physical or visible injuries. However, this isn’t always the case. All injuries or symptoms do not present themselves right away. In fact, it can take 24 hours or longer for soreness, pain, headaches and swelling to manifest itself in the body. After an accident, the body sometimes goes into the shock. This means that symptoms are hidden, and once the body is relaxed all the soreness and pain presents itself, sometimes overnight.
