Chest pain on the upper right side?

I am a 18 year old, 210Lb male who has been working out for a while and has just recently introduced chest exercises into my routine. Nothing extravagant, some resistance band exercises and push-ups for the most part. Yesterday I went for a run, approximately 3-4miles. During the run I received cramps in my kidney, under my belly, and on the right side of my chest. Now today when I walk I am having mild pain on the right side of my chest still, however when I sit, it does not hurt at all.
