I am 24 years and I am here to discuss my plight with you all. For the past 3 days or so I have been suffering from excessive cough and cold and my nose has been congested completely. My doctor is advising me to use a nasal decongestant. As I have not used it before so I would like to know from people-what are all nasal decongestants and how they work? Waiting for the replies!
