Hi , I am 18 years old male . I am suffering from fever since the last 15 days . When I take medicine it goes off but comes back soon after the medicine effect goes off . I've never had such a problem before. I consulted a doctor he gave me an antibiotic and fever tablets and I also went through a blood test . But according to the doctor the blood test is normal . But I ain't getting any better . It has been happening since 1st June and it's 15th June today . Along with fever I also have a constant headache and weakness . Kindly help please !
