Your son is having upper respiratory tract
infection I suppose. This can be the thick mucous collection which he threw out. No need to worry about that. First of all we need to control the running nose and cough
, so you can consult your child specialist/ENT specialist
for further management. Till then try using saline nasal drops 1 drop 3-4 times/day.
