Is it possible to fix my computer's mouse at home?

Hi, if you are reading this, thank you for your time, if you answer, thank you for your help. I have a computer that fell, my cat brushed her face against it pushing it off the table. The mouse is the touch-pad mouse with the two buttons underneath the pad allowing easier click/right click. Now the pad's buttons don't seem present and if I try to click, nothing happens. I don't even hear the small *click* of the mouse when I normally click. It seems a bit expensive to fix at the moment, is there any way I can kind of "home remedy" it? Preferably with no risk of breaking it further? If not, then it's fine to simply answer "no." Thank you for your time and help, if laptop type helps, it says "Lenovo" on the back.
