When you have pre-existing conditions, the significance of seeing a doctor soon after an accident is even higher. Any increases or exacerbations to the condition will need to be checked and documented for them to be recoverable. California law impedes the victims of an accident from seeking damages for pre-existing conditions, but that does not include a worsening of those conditions. For this reason, you must report any pre-existing conditions to your doctor and legal representation. Failing to do so can make it seem like you were hiding those problems to skirt the restrictions of suing for pre-existing conditions. Since you’re able to pursue damages that encompass a worsening of pre-existing conditions, there’s no reason to keep such information from your doctor or lawyer.
