I was trying to use symptom checker and it sent me here. In the past 3 days, after taking a laxative, my upper body feels very full. My bra hurts (feels like it s squeezing me.....never has before) and even when I take it off, I have discomfort, particularly around the bottom of my ribs on the left side but also in my entire upper body; chest, ribs, etc.. I am healthy and normally do not have ailments. This discomfort I am feeling is making me unable to get a good night s rest. It came on suddenly. I have not gained weight; I ve actually lost a few pounds. I am a little more tired than usual but I think the discomfort is making me feel that way.
