My son aged 5 .5 years admitted on July 29 with fever, high crp and esr  and treated with iv antibiotics and discharged after 5 days. He has recurrent infections on September and October and  treated with IV BOTH TIMES. When he had infection on October , a chest  x ray(opacity in right lung)has taken and again treated with antibiotics for 2 weeks (augmentin). His condition improved and subsequent chest x ray also improved. He  has developed fever a week after and antibiotics with iv is started . He has diagnosed adenoid hypertrophy for which he has been using nasal spray for last one year. Could you please suggest better treatment plans ?
