The back pain isn't too bad, nothing like what you've described Taurean & BR. I think it's mostly if I sit in a bad position, then when I straighten out it hurts - if I sit properly the whole time it's pretty good. Also thinking our work chairs might be pretty crappy, walking to the car after sitting for ages doesn't feel great!

Ah the joys of pregnancy
I remember those pains all too clearly...OUCH! I got so bad in the third trimester that I had to crawl to the toilet some nights. It was hell. It was like a pinched pain combined with muscular but it also felt like my hips just simply couldn't support my upper body! Kind of hard to explain but that's what it was like. Mine was always worse over night or when rising after sitting for a while, after driving, etc. Once I was up and about, the pain was there but it was like the muscles warmed up and the pain backed off, ITMS. My physio showed me a lot of pictures of muscles and ligaments in pregnant women and explained how they were affected by pregnancy. It was really interesting and made a lot of sense. The pain was awful though but it definitely improved, almost instantly once DD was born! I suffer a bit from back pain still and although it's a mild pain of what I felt during pregnancy, I think my dodgy back is the reason it still comes and goes.

I hope you get some relief soon hon.
