I had the SAME thing when I was pregnant. Toward the end of my pregnancy, the pain lessened. But, during the horrible pain, I had to use a walker, sit up at night, have my hubby help me get to the bathroom...it was HORRIBLE. The pain was manageable using Tylenol 3 and REALLY cold ice packs. Sitting in the water helped too. It was like a vacation from myself.
The neat thing about my pregnancy was that the bigger I got, the better it got. AND, I breast fed the baby for 7 months. ALL pain went away while I was breast feeding. After I stopped, the pain started in on me again. And this time, it spread through my whole back and ribs every night.
The pain was so bad that we are looking into adoption for our next child. BOY!!! Is it expensive!!!
