Postpartum question ( need help)

Diana

I’m 1 week and 4 day in postpartum but the past 2 days I been hurting and aching all over my body and my back hurts and my stomach. I know my uterus is shrinking plus I’m breast feeding but the upper part of my stomach hurts so bad. Including my boobs since I’m breast feeding. I tried adding a heating pad to see if it will help and nothing is helping I’m desperate for help. My back is killing me
