Hallow Dear, Your history is suggestive of some infection. Since you are getting fever with shivering, you are most likely having either urinary infection or Malaria. Please get your urine examined from the laboratory. If it shows pus cells and/or red cells, it is urinary infection. Then get the urine examined for culture and sensitivity which will identify the causative organisms and the antibiotics to which they are sensitive. Accordingly the treatment may be started. Please drink plenty of water - if possible, barley water. Also get your blood examined (thick smear) for malaria. Accordingly you may have to take antimalarial treatment. Possibility of genital infection should be kept in mind. Are you having any foul smelling vaginal discharge? Since you are in immediate post partum period, possibility of post partum sepsis should be ruled out. If such discharge is there, you can submit the discharge for culture and sensitivity. Accordingly suitable antibiotics will have too be started. The cause for such infection, like remained products in the uterine cavity, tear in the vagina, etc. will have to identified and managed. Please report to your Gynaecologist ASAP. Dr. Nishikant Shrotri
