Horrendous hip and back pain

Ki

Hey ladies, so I’m 30 weeks pregnant and for the past couple of weeks I’ve had the most awful hip pain, some days it’s really bad and travels to my back too, sometimes it feels a lot better. Yesterday I went shopping and possibly walked a little too much before work, and I was on so much pain for the evening. I ended up crying in pain just trying to get of the sofa to go to bed. Has anyone got anything that will help to relieve the pain. I use an exercise ball which helps temporarily and a bath. Anything else? Thanks.
