Many 'experts' think you can probably get 10 days out of cold cuts if properly stored (ie: not in the bag you bought it in). For me personally, since I have a huge aversion to being sick in any way, I only would leave deli meats in the fridge LESS than one week, 4 days maximum.
Postnasal drip occurs when the nose produces excessive amounts of mucus. The mucus may drip out the nose during the day, but when the child lies down at night, mucus collects in the back of the throat, triggering a cough. Postnasal drip syndrome is a common cause of nighttime coughing in children.
If you, or someone you are with, have night cough that is accompanied by serious symptoms, such as chest pain, a high fever (higher than 101 degrees Fahrenheit), or severe breathing problems, seek immediate medical care (call 911). If your night cough is persistent or causes you concern, seek prompt medical care.
