This is our 4th baby and pregnancy. I'm 7 weeks and aside from all day throwing up and nausea, my sciatica is killing me. I'm in dull pain all the time and sitting kills me. Driving is painful doing anything aside from laying on my side puts my lower back and hips in pain that shoots down my legs driving is painful do anything a side from laying on my side puts my lower back and hip in pain that shoots down my leg. Never had this problem in any pregnancy. It's shitty -_- ugh.
