<s>[INST] Hi my 5 years old son has asthma . He had his 1st attack on his 2 years old. But he always have fever after a month or every 2/3 months. On that time he complain abdominal pain . Every time dr said viral or chest infection. His checks gone very red and he got so weak cant get out of the bed. Can t eat anything on the period of fever that persists about a week. I am very worraid. [/INST] Hello, Bronchial asthma predisposes to chest infections. Infection of lower portions of chest may have abdominal symptoms as well. If abdominal symptoms repeat along with chest infection, the child needs to be tested for infection occurring at the same spot over the lower aspect of his lungs.  The child needs advice from a pulmonary expert, who could carry out the necessary special tests for him. Culture of sputum for antibiotic sensitivity tests is advisable to pinpoint the infecting microbe as well as to choose appropriate antibiotic. With modern treatment, childhood asthma is highly controllable. The child must be able to develop normally, without missing the school or the playground.  Wishing your son a speedy recovery from infection </s>
