If you are injured it's very important to go to a doctor for many reasons, and I'm not talking about making a claim. Of course that is important to be able to prove an injury, but just for yourself. If you have been injured it's very important to get prompt treatment, because the sooner the better. You don't want to have a long-term problem that could've been nipped in the bud by prompt treatment. So if there's any concern that you have after an accident, whether injury, pain, or any other unusual thing like a loss of memory or forgetfulness, make sure you go to the doctor as soon as possible, the sooner the better.
