Spasm started in right middle back then spread to my side now in the front right side under rib cage. i can't move without pain?

You need to be seen: Without more info it's not possible to determine what is causing your pain or how serious it is but the differential diagnosis (a list of every diagnosis that could cause your symptoms) includes gall stones, kidney stones, ectopic pregnancy, & pneumonia, all potentially serious problems that need to be ruled out sooner rather than later. If its muscle strain or indigestion you can sigh with relief
