I'm 24 weeks tomorrow and have been really lucky so far in the symptom draw, as in I've pretty much got this far symptom free. However for the last week I've been getting increasingly worse lower back pain. It's right at the very top of my bum and it's getting painful to sit or stand for any length of time. I'm at a computer most days so perhaps need to look at how I'm sitting but I fractured my coccyx about 8 years ago which doesnt help and am worried it's only going to get worse from this point on. I'm signed up for a fit back and bump class that starts next week but I wondered if anyone had found certain things or exercises that help?
