Pneumonia is inflammation of the lung. This is most commonly due to an infection. Inhaling bacteria or viruses is usually the way pneumonia is spread. Generally bacterial pneumonia will come on very suddenly while viral pneumonia will develop more slowly. Symptoms may include cough, chest pain, rapid breathing, shortness of breath, fever, chills, sweats, headache, weakness, tiredness, and a general feeling of discomfort and body aches. It is generally best diagnosed by chest x-ray in addition to a thorough examination. Treatment is based on the severity of your symptoms and the type of germ causing the infection. Antibiotics will help a bacterial infection, but will not help a viral or fungal infection. Over time your body's natural defenses will clear a viral infection. An antifungal is needed for the uncommon fungal infection.
It is probably fine to be taking an expectorant. You should also be sure you have an adequate water intake. As long as you feel well enough to be out and about you are safe doing so. If this does not resolve or continue to get better you should speak to your physician again. If the mucous changes to a darker yellow or green or if the amount is not decreasing, you should contact your physician who will probably want to order a chest x-ray. It can take a month or two to feel totally back to normal.
Call the doctor & tell their office your continued symptoms & ask them whether the doc needs you to have a re-check or perhaps a longer prescription of antibiotics. Generally, yellow mucous is NOT a good thing and signals some underlying viral or bacterial infection.
