I have a pain on the lower right side of my ribs. it gets worse when i move in certain ways and is only there sometimes. is it something to worry about?

Get an exam: With the information provided, I would suggest a doctor’s exam so you don’t have to worry. Pain generally is a warning for.the sufferer (unless it is chronic). Rib pain is often muscular, but can also come from malalignment, if there was trauma. It could also be referred from a difference source, so this is why a hands on exam become important; both to discover what it is as well as what is isn’t
