I had a virus for2 weeks-sore throat & head & chest congestion & rattly cough. Went to er for weakness etc. right lung a little tight. they gave me an iv & azithromax for a week-I took only 5 pills because the pills made me nauseated & I lost my appetite. Now into the 5th week I m eating a few chicken legs & vegetable soup & some fruit & water. Lost about 13 lbs. Very fatigued. trying in take to eat a few small meals a day & take a couple short walks. have discomfort in my stomach right side. Don t know what else to do to get better & have a better appetite & more energy.
