You can sue him in civil court for damages for assault and battery. Those damages can include your doctor bills and pain and suffering. For such a civil suit you would have to retain your own lawyer. In the criminal case, the prosecutors for the State of Georgia represent your interest as the victim in the crime. However, note that they do not represent you per se. You have the right to input into the case, such as what sentence to recommend, but they will make the decisions. Moreover, you can only get restitution for medical bills and lost wages, etc. You cannot get damages for pain and suffering, etc. Most cases like this are resolved in criminal court without a civil suit. However, if there are substantial injuries with good medical documentation, etc., and a defendant that has the ability to pay a substantial sum of money toward a judgement or settlement, then it would be feasible to bring a civil suit as well. You would need a lawyer to represent you for that. Good Luck.
