Help please !!

Last night I woke up in the middle of the night with chills and a slight fever.my left boob was a rock! It was hot !! I started hand expressing and without trying hard milk started coming out. I put baby on and he emptied my boob out but it still hurts and feels tender. It feels like I’m bruised up on my left boob. Baby is also not latching that well. Can this be mastitis??
