What is the statute of limitations for personal injury in Mississippi?

I was injured 8 years ago at a University. My professor asked me to pull down a projector screen that had malfunctioned. I pulled down and cut a tendon in my finger. The department put me on workers compensation but I was only a student. I did not receive a payment and the doctor bills are still unpaid. Every specialist that I visisted said that the tendon is torn but the surgery was complicated. I was 24 at the time and did not understand the procedures. I felt they got off too easy, I want to take action. What can I do?
