Sharp pain in left boob

🌻 Audrey`s Mommy 🌻
Worked out for the first time today at 7 weeks pp. We went running/powerwalking & I was pushing the stroller up hills. Now my c-section scar & surrounding muscles hurt a little, but most worrisome is I'm having a sharp pain in my left breast. I read that arm workouts can cause plugged ducts? Any experience with this?
