Has any heard of what the pregnancy hormone used to treat fibro? I ask because Feb 14th 2013 I gave birth to my 4th and final baby. Before getting pregnant I was dealing with life and my fibro. I was using medication to treat my day to day pain. When I found out I was pregnant I went off ALL medication. It was like hell on earth but I got through it. I wasn't going to take the risk. During my pregnancy I felt amazing.. I had almost no pain. 4-6 weeks after giving birth all my pain and fibro issues came back and worse then before. I found it interesting that I didn't hurt while pregnant so what is/was the hormone my body made that caused me to feel almost pain free???
