<s>[INST] my son is an active football playing 9yr old he recently complains of headaches at practices and his body becomes very hot he also has night sweats he does have asthma but is controlled and he has played three years with asthma just the last two weeks has he ever complained or had these issues [/INST] Hello, Welcome to Chat Doctor, Main predisposing factor for bronchial asthma is exposure to dust. As your son is having asthma he should be very careful. The symptoms will aggravate on exposure to irritant like dust. As he is having fever, headache and night sweat it might be due to invective agents in the body. Playing football requires a lot of energy and a lot of fluid will be lost during playing, loss of fluids and electrolytes in sweating may also lead to your sons symptoms. He needs to HY Chat Doctor. Thank you. </s>
