I have chest congestion. At night when I lie down to sleep I can hear my breathing sound its very irritating. It comes at night only or if I lie down. In just 20 minutes I can feel congestion in my through and in 30 min I am able to spit out almost 10 ml puss from my mouth with one cough. I do this every night 4-5 times till morning. It's been 20 days. Help me I tried cetrizine/ cough syrup etc but no help I do not drink cold water or drinks I avoid fried too. With cough I can spit out the puss generated in my body but it should stop.
