Not criminally. Only the DA will press charges against an alleged defendant. You can report it to the police who will forward a report to the DA to see if they will press charges. The case is stale (old) so I doubt the DA will take action but who knows. You can hire a civil defense attorney for the injuries and costs thereof but again the case is stale. Proof issues will be difficult at this late date . Good Luck! Seek a free consultation with a private civil attorney.
Only the government (the DA or bother prosecuting agency) can file criminal charges. They don't do any independent investigation - the police do and submit the reports for review. You can start with making a police report. Because of the passage of time, it will be an uphill battle to prove this.
You can pursue a civil personal injury case against your assailant, but if you are considering that, act quickly as there may be statute of limitations issues.

The longer a person waits to start up a claim the weaker a case gets. The only way to get this person charged in criminal court is to get a prosecutor to charge the case. This will be difficult becauase of the time. Legally he can charge it because a simple assault usually will have at least 2 years attached to it before it can't be charged but again, it is weak. If you are asking if you can sue this person then you need to ask a civit litigation attorney about that.
The other answers are correct. If you wish to sue the deft for your injuries/damages, see a local injury lawyer asap. keep in mind that you have the burden of proof. Can you prove the deft attacked you and caused these injuries?
Also if you are interested in suing the school for some reason, you had 6 months to file an administrative claim to get that ball rolling. You hav two 2 years to file a civil personal injury case against the attacker. In addition to proof problems already addressed, you would have to make sure he has insurance or significant assets to pay you. Also, your damages will be difficult since you had a pre-existing condition and an agravation of same. Not an easy case, but you can explore it with a pesonal injury attorney. Good luck.
