Drink water. That's where kidneys are. I get that pain sometimes too drink lots of water and it goes away.

@busymomof6, I’ve tried everything my dr says it’s Braxton Hicks but this constant all day every day

Warm bath, heating pad, pillow between your knees, pillow behind your back, ...

I have sciatic pain and sometimes I roll on a tennis ball against the wall. Helps some. Hope you find relief.
