After pains

I've had stitches and I'm in so much pain moving around and sitting down. But at the end of the day around 5/6pm and onwards I feel so ill! Short breath. My ribs hurt and my upper back. I don't whether it's because of my boobs? As they are so heavy or because I have a cough. I just don't know 😩 it's been 4days since I had her, everydays a little better but don't know if this is normal?
