What causes pain in the lower left back-side? - side lower back pain causes more condition_symptoms

My back has been off for bidding on and leave for a month. But the pain seems to come out of my body to my left kidney, and I do not know why. I'm really bad when the gas, where the chats, etc.. This is not my gallblatter, or a plant, but im not sure.
