I never had it with my other pregnancies. It started a couple of days ago on the left side and is killing me. Tonight us the worst, I can barely walk. I did some clean up and putting away the Christmas tree and all that so the fatigue accentuated it I think. Am I screwed for the next 3 months? I am 27 weeks. will it go away? Obviously I am asking for your experiences, not Internet doctor diagnosis ;-)
I've only had that kind of pain twice but both times I used a Thermacare heating pad on my lower back/bum and it helped a little. It's no joke though - very painful!
I had bad sciatica for about 4 weeks, then it went away (now I have rib and pelvic pain, so don't be too jealous). A pregnancy support belt really helped.
