Backache remedies?

Kate

I'm pretty much at work on my feet all day long and 31 weeks pregnant and today has been the worst for my back. Anybody any ideas on how I can help it not hurt as bad? I already have a bellyband didn't really help today. I'm laying down for the night but I can barely walk it hurts so bad. Any relief or advice would be great. I took some aceteminaphen, but I'm not sure where my heating pad is either. So anything else would be great!
