Just curious

Ever since I hit my second trimester, I've been in a tremendous amount of pain. When I walk I hurt, when I sit down I hurt, I can't even bend over my whole body just throbs, my back, legs, ribs, hips sometimes it feels like I have pressure on my chest .But I just recently discovered if I lay flat , the pain eases up a lot! I get dizzy, I stay really hydrated. My doctor says I only have ten weeks of pregnancy left, but if I'm still hurting like this on February the 6th they'll look more into it. Has anyone else went through all this pain. This is my first pregnancy so please no rude comments, I'm just nervous and scared all together.
