My stomach is hurting terribly. I just ate breakfast made me feel somewhat okay but that sharp pain is still there. I have goosebumps also?

May need attention. If abdominal pain persists and intensifies (goosebumps), especially if associated with fever, then one may need urgent eval. Only you can gage what "terribly" means. If 10/10, then go to the emergency dept, or urgent care. If 2/10 and subsides with mylanta or maalox, then call your doc on monday for further eval.
