Is this normal?

I'm 26 weeks and experiencing a lot of pain. I'm not worried something is wrong because it's not like cramping or anything. But my entire stomach and my entire back is hurting terribly. No matter how I lay down or sit up, they hurt so bad. Nothing seems to help and I'm on the verge of tears here. Has anyone been through this? Is it something to worry about? I never experienced anything like this during my first pregnancy
