Sharp shooting pain...

Jenna
I started pumping 2 days ago bc my baby wasn't sleeping at night so I was concerned he wasn't getting enough milk out of me. Turns out my supply is low. Anyways, I woke up during the night with terrible sharp pains deep within my left boob and also a bad burning sensation. I tried pumping bc I thought I was engorged but it didn't help. Any ideas on what's happening!!
