I went to the Dr. Monday and he gave me the Z-pack for upper respiratory infection. Today is Thursday and do not have a sore throat anymore but my nose is constantly running (I am blowing so much) and both nostrils are completely stopped up causing me to breathe thru my mouth. He also said I could take Mucanex D but it does not appear to be unstopping my nose. I have put Vicks around my nose, gargled with warm salty water, and even boiled water and held my head over it with a towel (which only opened it for about 10 min). Any advise, should I call the doctor back and ask for Amoxillian or something else? How can I unstop my nose where I can breathe. I used Afrin last night and it opened me up but I am afraid of getting addictive to it, thanks,
