| | Could I have pneumonia?
First off, is this a progressive infection? If it is, it's been about a month since I first had some unexplained symptoms. When it happened, my teeth chattered(I don't remember if it was like a chill) and then a few seconds later my chest felt tight and heart rate increased. Went to the ER that night and they did an EKG, blood tests and a chest X-ray and everything was normal. Now every once in awhile ill get these flare ups where it happens again but with no teeth chattering but what feels like my sinuses on one side I can feel pressure and I can't really breathe. Afterwards I feel worn out for a bit. Also my nose has been stuffy for a long time now. Please help
