You qualify for financial compensation if you had a pre-existing condition aggravated by an accident that wasn’t your fault. You may not receive as much compensation as you would receive for receiving a new injury, but you may still be able to hold the at-fault party responsible for aggravating your condition and thus financially liable for any medical bills, lost wages, etc. sustained due to the injury aggravation. However, cases involving pre-existing conditions can be very complex, so it’s very important that you hire a lawyer if you’ve had a pre-existing condition aggravated by an accident, as a lawyer can hire experts to prove that your condition was aggravated by the accident.
