I ve had a mostly dry cough , and a runny nose for 4 days now. I also have a feeling of toughness in the lower part of my throat and upper chest . I m not sure if I ve had a fever, but I have felt tired and run down. Sometime yesterday my voice started getting hoarse and I can t take a deep breath. If I see my doctor, is there anything she can give me to help, or should I just wait it out?
