Mastitis

Friday night I started feeling flu like sinthoms and I told my husband I just felt sore muscles, by Saturday night I felt shaky and still sore and strong headache also really strong pain on both of my breast. Hubby wanted to take me to the ER at 2am but I told him I didn’t think this was an ER situation. I am sure I have Mastitis bc I got it with my first son and it was all the same sinthoms while I was breast feeding. I will call my doctor tomorrow morning hopefully they can see me right away. But I am wondering, if I already know what it is, should I go to the ER, to Urgent Care... Today I felt so weak I slept throu the whole day. What would u have done?🤷🏻‍♀️
