Hello, My 7.5 month baby is crying a lot through out the day . While giving bath today, on touching back of his ear, he started crying a lot. And he is constantly trying to pull his one ear (left). He also has low grade fever since yesterday and very Cranky and fussy. Hez taking adequate feed. Last week we have him relent and normal saline nebulization upon advice from is pediatrician as he had chest congestion and fever. What could be the reason. Kindly help. Thanks.
