My Wife Was Diagnosed With Pneumonia About 8 Days Ago

My wife was diagnosed with pneumonia about 8 days ago (Showed up in chest x-ray - type unknown). I'd been taking care of her the whole time she went throught it. After her diagnosis, she took the Z-Pac regimen. It took her about 6-7 days before she felt fairly normal, but still had an occasional cough. We were usually pretty good about her covering her coughs and not using the same dishes, and utensils, but we did share the TV remote without disinfecting it. I've now had a productive cough for a little over a week. My energy level is low, but I can still do things around the house, yard and garden. It tires me quicker than usual, but other than that it's not too bad. My prodcutive cough's sputum seems to get worse when I drink a glass or two of water. The sputum can be quite concentrated and is a light yellow-ish green with tiny air bubbles in it. It is also more productive if I lean to my right when coughing. I don't believe I've run a fever during this time. Any thoughts or recommendations?
