I met with a physical therapist this week, and she's determined that a lot of my problem is because of a previous car accident that I was in several years ago. That means that the back pain I'm experiencing will probably continue to get worse until the baby comes. Bummer.
On the other hand, about three months after she's born, I can start PT to rehab from the old injury. That means I shouldn't go through this for subsequent pregnancies.
Sort of a good news/bad news thing, I guess. Still, I'm trying to stay positive about it. My mobility is fairly impaired already, but circumstances just happened to work out that my mom moved in with us until after the baby is born. Sometimes things just happen they way they should!
