Most brain injuries require extensive medical care. As a result, you could be entitled to recover for your medical expenses, both past, present and future. Additional compensation can include monetary compensation for loss of work, both past and potential earnings you lose as a result of your injury. Pain and suffering is also common and you could receive compensation for such. You may be entitled to compensation outside of any insurance claim which is why you need to obtain legal advice prior to agreeing to any terms with the insurance company.
