Do I have two years from a unnecessary personal injury lawsuit to seek a lawyer?

Two elevator doors by my apartment had been programmed that on the fifth time the door closed it came fast and was not stopping for anyone or anything. The programming was admitted calling it "the nudge." It hit me and I landed on the back of my head and across the hall. I have permanent hearing nerve damage. I asked for my medical expenses for five years and they want to give me two. If I have to seek a lawyer I will ask for ten.
