can a change in beds cause your rib cage to feel weird

It is unlikely that a change in beds would directly cause your rib cage to feel "weird." However, sleeping in a new or different bed may lead to changes in your sleeping posture or support, which could potentially affect the alignment of your spine and rib cage. If you experience discomfort in your rib cage after changing beds, it may be related to these factors and it is recommended to speak with a healthcare professional for further evaluation and advice.
