Sore throat
You may develop a sore throat [4] as a result of the flu. There are two main reasons this happens. The first is that persistent coughing can irritate your throat and make it sore. The second is that the flu virus inflames some parts of the throat and makes the throat sore.
Sore throats typically worsen as the flu worsens. Drinking water and swallowing foods often become more difficult and may be painful. The condition improves gradually as the infection improves. There is no instant cure for sore throat, but there is an abundance of folk and home remedies that can aid recovery.
