It's not recommended and most obstetricians will tell you absolutely not.  However, if your chronic pain is severe enough that you don't feel you can make it through the pregnancy without something stronger than acetaminophen, you might consider seeing an obstetrician who specializes in high-risk pregnancies.  They have more experience in administering pain medications during pregnancy. 

One of our community members – Nicole – has wrestled with these issues, successfully dealt with her chornic pain, and had a healthy baby.  She has kindly been willing to share her experiences with all of us.  Here is a link to her first SharePost: My Journey through Pregnancy ... and Chronic Pain.  You can also click on "View All of Nicole's Posts" below her name to read her other SharePosts.  Or you can click on her name which will take you to her profile.  From there you can send her a private message if you like.

We also have a great thread on Pregnancy, Motherhood and Chronic Pain in our forum (started by Nicole, whose user name in the forum is IceCreamGoddess).  There several women have shared their experiences.
