Back pain?!?

As

I seriously am walking like an 80 year old woman. My back is so tensed up and bad with this pregnancy. I tried getting a prenatal massage today which helped while the massage was happening. Now in a warm bath trying to get my muscles to loosen up. This back pain is seriously going to be the end of me. I can't even reach down to pick up something off the ground. I have heard of ligament pains, but back??? I have an appointment on Monday. I'm hoping doc will have answers. Honestly I'm used to this pain in later months of pregnancy, but not this early. Anyone else???
