Hi Laura I didn’t wear with my strapping one only the last 2days I wore a loose one (orange one from h&m in my pictures) because it felt looser ! My strapping was pretty tight at 1st I could only take shallow breaths and would get out of breath so easily, it could just be the bruising on your rips rubbing with the strapping just make sure you take lots of pain relief and I’ve to help with the swelling.
