Lovenox warns of epidural??

Hi ladies... I don't really post on here much but I figured I would come here for this. I am on lovenox due to clotting disorder and recurrent pregnant loss. Anyway I was reading on the lovenox site today that having an epidural can cause paralysis. It goes on to say it is even more likely if you have any spinal issues or spinal surgery. I am a little freaked out about this because I had a spinal fusion due to spinal problems. I am obviously going to talk with my doctor about this next week but I wanted to see if anyone knows anything about this.
