Can I bring a lawsuit against my apartment complex for negligence?

Earlier this summer, brand new window shades were installed in every apartment in my complex, but apparently the window shades in my apartment were installed incorrectly; they were not fastened and locked in correctly. Here is what happened, upon waking this morning, I tried to draw the shades up to listen to the morning rain--this is the first time I have tried to do this since they were installed, and the whole apparatus fell down on my face requiring me to go to the ER where the doctors were able to stitch a small but bloody gash (three stitches). I use some force pulling down the string, but not much. I will have hospital bills and a permanent scar on my face as a consequence of this. Thanks for any assistance. Mark
