4/5 days po. Mildly Sore left boob & sore left middle of my arm. x Started by: Tilly

Hi girls, I’m 4/5 days po & my right side is great,no pain & feels good. But my other side(left) feels sore & seems to be taken forever to settle. I’m also experiencing mild soreness in the middle of my left arm & mildly swollen. Is this normal ?? X

Also my left boob was a tiny bit smaller than the right side.
