What causes low grade fever?
Patient: My 8 year old son came on Friday with a pounding headache and went to sleep at 6:00, very unusual for him and since then has been spiking a fever every night the highest being 103.5. He has also been very lethargic during the day with a low grade fever. Doctor: Hello,Hope your son is feeling better now.There are several reasons for low grade fever. I would suggest you to get his blood work done  (compete blood count, Differential blood count and also blood culture)For the fever you can give him paracetamol till the time reports are out. In case of any infection, the doctor would start with suitable antibiotics.Take good care of him.
