I was hit multiple times by a semi while driving for work in a company car. It was a third party claim handled by WA L&I because it happened while on the job...but they closed the claim right in the middle of medical treatment for neck injury and headaches, leaving me with medical bills. L&I claims that the reason I havent healed after 5 months was that I have a preexisting degenerative disc disorder...although I never had any neck problem/headaches before in my life, and they onset at the time of accident. with continued pain ever since. What kind of lawyer do I need to protest the claim closing and get the continued medical care I need from the third party trucking company.
