Hi, i think this is most likely to be due to the tightening feel you get after having unders, i literally felt like someone was sat on my chest and breathing was defo more difficult. I didnt have a band either, just dressings on my insicions. I felt this way for first couple days and then it eased up alot. But as the girls above have mentioned i would maybe go to a nd e to be on safe side as its better not to take any chances, im sure you will be fine tho xx
