if i was assaulted at a bar by the bouncers and had major injuries can i sue

i was assualted at a bar and although i do not know if a certain person or the bouncers assaulted me, but the police report had different stories from witnesses. we went to court and there were witnesses who said they saw the bouncers hit the door with my face. i still don't know who did it. but i am disabled and would like help with my doctors bills. is the bar somewhat responsible for any of this. - Is this your question?
