How can fever that occurs every night be treated and cured?
Persistent fever follow up.
I think the fever is caused due to your viral state and your doctor supposed that it will go away by itself since he didn't gave you antibiotics.
You can take paracetamol or ibuprofen to lower the fever. Take a 1000mg dose to lower the fever. It didn't get lower first when you used a lower dose.
If it doesn't go away in about a week you should visit doctor for a blood work.
Other diseases such collagenosis, or blood disorders can be suspected.
Hope I have answered your query. Let me know if I can assist you further.
