Mastitis ?

What were your first symptoms? I was feeling extremely cold earlier and now I’m feeling just so off/ feverish… my breast is also in si much pain!! No matter how much I let my baby drink or how much I pump I feel like I cannot get enough out it hurts… temp is only 99.1 when I checked 30 min ago… wondering if this is the start of mastitis and what other signs I should watch for ! Only a few weeks pp also! So kinda freaking out about other infections…. Husband isn’t very worried but this came on suddenly today and idk I just feel weird and not great….
