Really bad upper back pain!

I have gotten it with every pregnancy. It is just to the right of my spine about the middle of my ribcage. It starts around the last 10 weeks of my pregnancy. I asked my obgyn about it with my first and she said that some women experience ligament strain and even tears, and that my ligaments are probably torn. It feels like there is a spike in my back and though some positions are worse than others, there is no way for me to get it to go away. I'm very short waisted and there is no where for me to carry a baby but straight out, plus I have 9 pound, 22 inch babies, so it is really tough on my ligaments. I also have ligament pain about 2 inches in from my breastbone that is approximately where the spike would come through the front. I think that is because my kids always have their butts right under my ribs there and it's really hard on the ligaments when you can only get so much torso space.

I tried the belly support, but didn't find it to do any good so I quit wearing it. I just suffer through. It's funny, though, because I can tell immediately when my kids have dropped during labor because the back pain suddenly goes away.
