Im facing severe chest congestion. I visited Dr. T.N. Shetty in Bandra and I've completed his prescribed dosage of antibiotics to prevent the bacterial infection in my body, antihistamines, bronchodilator and antacids. Yet my condition hasn't improved. I'm a singer, so I need something to easen up my larynx and need to get rid of the phlegm in my chest. The phlegm colour when I wake up in the morning is a darker shade of yellow, and I need to improve my immunity, prevent a chest infection and strengthen my lungs. At the moment its hard to taste my food because my nose seems to be blocked most of the time. Please prescribe me medicine that will help my situation.
