Lawsuit for slip and fall?

i was snow blowing a guys driveways and slipped and messed my back up..i was snowblowing him out so he can go take care of his business and plow the lots..i need to know if i can file a suit against him..because he knew the conditions of the weather..and i immediatley approached him that i had fell on the ice and he didnt ask if i was ok or if i needed to go to the ER..he is a business man had his own plow..snow blower..he was actually a friend of mine but we are no longer friends..he told me that he would also pay me to do it i didnt get paid till this day...serious people only no smart remarks pls
