I didn't even try to sit for the first 4 weeks, just lying or hunched standing. After that I was in a hard chair (couldn't handle a settee), I remember getting out of a car was a real chore for 3 months or so. So yeah it should ease, that said although it was all uncomfortable, I was able to discern and improvement over time...
Keep an eye on it, perhaps keep a pain diary recording what it feels like (burning, stabbing, tearing, tingling etc) and the intensity.. also note the type of surface and duration to help you determine if it's getting better.. when your in pain in can seem to last forever, but in practice your probally recovering well.
If you cant see it, definately mention it to a doc..
