Retirement accident – Pain allowance

Hello all, I am an early retiree, had an unincurred reversing accident on 10.05.2019. The opposing insurance has already taken over and paid the damage of my vehicle. But they do not want to pay me any pain money. I was after the reversing accident with my family doctor, who diagnoses that I suffer from the consequences of an HWS distorsio (S13.4., G), belly cover bruise (S30.1, G). I have submitted the medical certificate to the opposing insurance. can you please give me further information/assistance? Then I have a second question: The opposing insurance company paid me the money for the damage I received from the insurance company due to an expert’s report from a car repair shop to which I sold my vehicle unrepaired. Now the expert wants to pass on the money for the damage I paid from the insurance company to him completely. et. In this case, do I have to transfer the full amount to the evaluator? Thank you very much in advance.
