I've suffered from pretty severe sciatica in the past couple of years. I ended up getting signed off work for 3 weeks and had to hand in my notice and quit my job as that was causing the problem. I've since recovered pretty well.
I'm now 12 weeks pregnant and it seems to be returning. Just on the left hand side. If I sit or lie down for any length of time, my back at the bottom is excruciating when I move and I can't put any weight on my leg for a couple of minutes. Please tell me this isn't going to last the whole pregnancy?
