My age is 26 years. . I am a patient of functional bowel disease. I easily get cold and sneezing . But most difficult problem is every year I got fever 2-3 times and it doesn't go away at least 7 days suffering , paracetamol can not lower the temperature , antibiotics can not work but this time no sneezing , no cold , suddenly fever. Has any vaccine so that if I take it then whole year I will be free from getting fever. It is said worthy in this pertinent that I drink water only boiling and then cooling and every time before taking food use soap to wash hand . But still this is happening.
