I have some pretty intense pain in my lower back mostly at night. it's in my lower back. i've had this pain for almost 6 years. it was after my second daughter was born. i had flinched when i was getting an epidural and felt it grind against my bones. was worse when i became pregnant with my last child because all my bones felt lax and my lower back felt as if it were shifting when i moved in some ways. now i can't bend too far(can't reach my feet nor my shin) because of pain when doing so and the night pains are terrible cause it feels as if being squeezed with rocks. this pain is like this half of a month not daily though.
