What is the best thing to do to relieve cold/bronchitis symptoms when doctor is away?

Symptom control: If you are not having fevers chances are it is a virus and you just need to utilize symptomatic relief...Cough suppressants, mucolytics, and anti-histamines can help as can sudafed if you are clogged up. I like to use the nety pot w/ distilled water to help clear sinuses. Give it time...If you get a fever you may need antibiotics.
