Mastitis help

I’m no stranger to mastitis. I had it twice with my first. I was able to avoid it this time when my milk first came in but now we’re at 7 weeks and I started getting it yesterday. No noticeable redness yesterday but sensitive and pain underneath my breast. I had fever, aches, pain, shakes. I used hot compresses with hand expression then ice. I took a long bath and shower milking my boob more. Rough night with sweats and pain. This morning I woke up and felt like crap. I’ve been taking 3 ibuprofen around the clock almost when the fever returns and I can feel it. I’m wondering if I can kick this on my own or if I need to go in to get antibiotics. Oh and I’ve been taking lecithin. I’m thinking I can tough it out today then go in tomorrow if it doesn’t get better? Has anyone had experience getting through it with fever and body aches and how long it took to get over it? I was having what felt like abundant supply last week then the last two days I haven’t been as engorged so I don’t understand why I got it but this week exactly is the same week I got it with my daughter. Glow said this week baby will go through a growth spurt. I’m offering my breast often anyways to get him to suck it out!
