I had sinus infection 2 weeks ago. Had cough...headache. Treated with prednisone and antibiotic. Head congestion went away as well as cough. I m left with shortness of breath...weakness all over body doing my normal activities. I have chest pain...pain around to back. Feel like a rubber band is around me. Dr heard some sound in lungs when examined and diagnosed with sinus infection. I had finished my meds, then had major diarrhea 1 day. I m too fatigued to stand long enough to cook a meal. I feel kinda like a virus. After doing a small chore have to lay down or sit down because of bad shortness of breathe. Not sure what to do at this point. I was going to go to urgent care this afternoon but they closed at 4pm before I could get there.
