Hi, my son have cold from past 4 days, i giving him the regular medicine our doctor prescribed (alaspan ag & levolin). our doc says no need to visit him, as my son doesn't have fever or other symptoms. he have bad cold, (not runny rose) but lot of mucus. he snore lot while sleep. i can feel t cold in chest and back, like vibration while snoring. no cough or sneezing. should i be worry, he doesn't like to sneeze the mucus out. i give nose drops while sleeping. when should i visit or consult doctor if cold doesn't come down. anyways to take out mucus.
