Plenty of accident survivors feel perfectly fine immediately after an accident but then feel sore and stiff or have difficulty moving around after several days following the accident. As soon as you feel any delayed symptoms after your accident, see your doctor immediately.
Explain to your doctor all the details of your accident, what you did after your accident, and exactly when and how you felt when your symptoms suddenly kicked in. Certain injuries, like a traumatic brain injury (TBI), chronic pain, or herniated disc, could take longer to manifest, and only competent doctors could determine whether injuries like these resulted from the accident.
Seeking the right medical treatment for the injuries you suffered from an accident helps diagnose and treat your injuries and document your symptoms. Ultimately, it will help you prove that your injuries resulted from the accident.
