Pain at 21 weeks

With my daughter I had it but not this badly, I remember being told there's nothing I could do BUT do any mommas know if any way to help this horrid pregnancy (I guess growing pain) when I'm laying, sitting walking it's a huge pressure on usually both sides more so on the right side but it feels like it's under my boobs or my upper rib cage, feels bruised, sore to touch or like a car ran over me, it's horrible, I can't sleep at night because of it. What's a good way to comfort it or help it?
