Braxton Hicks?

So, last night my back hurt so bad I couldn't move and it also hurt in my upper belly below my boobs. It was like a hard pain for like a minute and then it would die off a bit and then I'd try to readjust and it would happen again. I also felt like I needed to push to make it stop. Idk if I had major major gas or if it was a Braxton hick. That pain happened about 3 or 4 times before it stopped. I tried rolling over, a pillow under my butt, back, legs, standing, sitting in a rocking chair, nothing helped. It hurt and was very uncomfortable. But baby was kicking around the whole time. I'm 28 weeks now.
