ok it started front side left side fullness like something was in there, it since has caused me shortness or breath, which I think is anxiety from worry, I have now been having pain along lower ribcage and under left front ribcage. went for U/S to rule out stone, urine clean no issues there. I have left flank back pain , that travels along left side of spine. Im scared to death. I had a CT scan done after advised from US results to rule out Stones. I alos had chest xray about 1 mth ago that was ok? Confused and frightened??? any thoughs??
