hello dr...my 8years old child was feel cough, sneez,blocked nose few month before these illness came with my child ,this is allergic or not I test the blood??

A. Hello good morning !! General cold ,flu and cough cause blocked nose ,sneezing and throat pain . And these take 5-8 days to recover ,use medicine as prescribed by the Doctor. Only concern when the baby has often cold ,flu symptoms ,phlegm accumulation ,breathing issues otherwise no need to worry.
