my dad is suffering from blood infection as doctors say, last year he had dengu and some blood was supplied to him... since then there was no problem but after 1 year he had a eruption on his nose which took two weeks to settle down during that he had high fevers also.. once the fever was over now he is again having little fever and he has lots of pain while passing urine and stool. his colour is also turning pale. what could be the reason. is it really the symptoms of blood infection???
