My son has red bumps big and small all over his body some on his face and a few on his head. What could it be? No itching and no fever but very cranky

Could be simple rash. This could be something as simple as 'heat rash' or acne although acne would be my second consideration. I would recommend that you see your pediatrician to verify exactly what this is.
