Shivering , sweating, headaches and body pain

Fio

I am 13 days post partum and everything hurts. I get sweats, then shivering and super cold, then hot again. And I have a constant dull headache. My legs are a bit swollen. Just feel sick with no strength all day long.

I went to emergency after one week postpartum as I had tissue coming out and other pains and they ruled out infection, and confirmed via ultrasound there is no placenta left inside.

Anybody having this symptoms?
