I went to the ER last night with severe right flank pain. I've had kidney stones before, but only once this pregnancy. At 12 wks I was told I had 3 in one kidney and one in the left. Now, at 24.5 wks, I was sono'd and I have at least 5 (+ more smaller ones) in each kidney, including a large (7 mm) stone in the left kidney. This sucks. I'm on heavy painkillers, but still vomiting. I think I'm going to have to go back in to to hospital if the puking doesn't stop. Ugh.
