Factor V Leiden is a genetic clotting disorder. It basically raises your chances of getting a blood clot. Alot of people have it and never even know it. Some women find out when they go on birth control and end up with a pulmonary embolism. In my case I got one in my IV site after I had my son. That one was in my left arm and bad news because it could have traveled to my heart. I was in the hospital for almost 2 weeks with that one. The second was at my IV site after I had my daughter 19 months later. At least it was in my right arm that time! Much shorter hospital stay, thank goodness. They tested me for clotting disorders while I was in the hospital and it came back positive for Factor V Leiden.
You know what's scary? Both times I knew something was wrong before I was even released from the hospital after giving birth. (or, more precisely, laying on an operating table while the doctor did the work
I even asked the doctor that released me if it could be a blood clot. Her exact words were "You can't get a blood clot from an IV site". Over the next 2 weeks it traveled from down by my wrist to right below my elbow. It was unbelievably painful and just plain ugly to look at. I called the office first thing one morning and they got me into the office. Even after looking at it, they didn't think that it was a clot but they sent me for a doppler of my arm to be on the safe side. After the doppler they sent me straight to the hospital. Thank God they did. That night it broke up and landed in 5 different places up my arm and shoulder. The one right above my elbow was the worse. I have a stretch mark from where my skin stretched so much from the infection.
The first time I could excuse because it was my first one. The second time I kept a close eye on the site and, sure enough, there were red streaks on the 3rd day. I explained my history to the nurse and she just blew me off! Even the doctor that released me didn't think that it was anything. (of course, it probably didn't from across the room where he was standing!) I ended up going home and calling my internist. She got me into the office that afternoon and by the next afternoon I was back in the hospital. A different one than I delivered in, of course!
I ended up changing OB/GYN practices after that. I loved my OB but he is part of a huge practice and you never knew what doctor you were going to get.
