I am have symptoms of what we refer to as a head cold (running nose, congested nose-one side, itchy nose and sneezing and sinus drainage, slight coughing. At first when I sneeze I was having a slight pain in my back almost under my arm on the left side, and it would go away almost immediately, but now the 3rd day, when I sneeze and cough, the pain is sharper and it last longer and if I move right after sneezing or coughing, it hurts worse. It hurts when I clear my throat, it hurts when I breath hard and it hurts when I pull air through my nose to dry to get air because of the congestion) some one told me I probably have gas
