What Is The Pain Below My Right Rib Cage After A Workout?

light pain below my right rib cage(opposite side of heart) and above my waist line -2 hand lengths right of belly button. it is not a sharp pain more of a bruised feeling...i worked out last night using a resistance band mostly on my chest- many things are going through my head such as stretched muscle ,hernia, kidney stones considering the area of the ureter, what should i do if this pain persists
