If you are coughing and sneezing a lot, there are a few things you can do. You can try using a saline solution to clean out your nasal passages, which can help reduce mucus dripping down your throat and causing coughing. Drinking plenty of fluids, both hot and cold, can also help relieve symptoms. Using throat lozenges can help ease any irritation in your throat. If your symptoms persist for more than 7 days without improvement, it is a good idea to see a doctor.
