I never had lower back pain like I have right now. This morning, I bent over to reach something from under the sink and a sharp pain shot from my lower back down my left leg. I have had this sever pain all day. It hurts to sit, walk, stand. I am not sure what to do. Could turning or bending wrong cause this? I am very gassy for some reason as well, not sure if that is related but it feels like it is. I don't have the money or insurance to visit a doctor so please give me some ideas on what it can be and how I can do self help. I am only 25 as well.
