Home remedies?

I'm 2 weeks pp, I both breastfeed & pump for my daughter. Yesterday, I woke up wth a sore throat & today, I woke up feeling even worse. My neck & back are killing me. My sinuses are killing me, my head is pounding & I feel like I'm swallowing razor blades.. I haven't taken any medication because I'm afraid to due to the fact that I'm breastfeeding so please help me out here ladies!! Thank you
