Query: Very uncomfortable

I I am 25 weeks and bought this belt to help me with my back pains and got no results. It is very thick and sits all around your back. If you work all day and have to get up and down, the belt will slide up your back and you'll need to go somewhere to adjust it because you can't just pull on it to get it down. I showed it to my doctor and she said it is not the best product, something smaller will work better, but if you really suffer, consider physical therapy.
