I am having common cold for more than a month now. Generally, I get runny nose when I wake up in the morning. Sometimes, I get a chain of sneezes as well. Most of the day remains normal. I have taken multiple medicines to cope up. Initially I took NamCold, then Levocetrizine, then Cinarest. And finally took some Azithromycin. But, nothing is helping. Please suggest some cure. Thank you so much.
