Anytime you experience significant chest pain, you need to get medical attention. This could be due to muscle strain or even a simple bruise, but it may be an indication of more serious internal injuries. Chest pain after a car accident is extremely common because drivers and passengers can strike other things in the car like the dashboard or may even suffer injuries when the airbags deploy. 
Inertia from the sudden force of a crash throws the occupants inside the vehicle forward, leading to pain in the front upper body.
If you believe you’ve suffered chest pain after a car accident, you need to get examined immediately. This gives you the best possible opportunity to understand your diagnosis and to get treatment started. Early documentation also makes it much easier to pursue compensation with your insurance company or in a lawsuit.
You will have to ultimately show that your chest injury is related to the accident and that it is another driver’s fault due to their breach of the duty of care. You’ll want to speak to an attorney who is experienced in helping people injured in vehicle accidents. Many lawyers have helped people suffering from chest pain in accidents and may be able to help you recover compensation to pay for your medical bills. Although it can be overwhelming to navigate the legal process on your own, retaining a San Francisco chest injury attorney makes it much more likely that you’ll be able to get the support that you need.
