Try Filling A Long Thick Sock With Rice! Tie it , Heat It In Microwave For A Good While Take It Out Use As. a heat pad does miracles trust me
Try and sit down as much as possible. I was on my feet a lot for my job and my back would kill me by the end of my shift. I stuck it out until 38 weeks but it was soooo hard. Warm bathes and heating pads saved my life. Also good for hip pain.
Same here my back kills me from working on my feet for so long. Going to get a belly band soon and hopefully that'll help!
