I have same like a thread jelly phlegm.everytime i strted to cough it will continue onward for how many days or weeks.like a slimy sticky thread like?

Sticky phlegm : Try irrigating your nose with 60 cc if saline to each side 4 -5 x a day. The saline is made by adding 1-2 tsp of salt to one quart of water with a pinch of baking soda. You can keep the mixture in the fridge and the cold will be soothing. It can be tap water if you have good water. Otherwise use bottled or boil the water. Ensure that the water is room temperature before putting jt in the nose.
