Girls, I have a question for you. I had a cold, now I'm starting to recover slowly. There was no cough, there was a runny nose and a slight temperature and that's it. Tomorrow I decided to take a test for the crown just in case. So here's the thing: as I started recovering, I got shortness of breath. More precisely, I usually breathe well, everything is fine, but when I want to take a deep breath, inside it feels like something heavy, like something in my throat, above my chest, something heavy, and coughing with a full breath often (sometimes). I, of course, think about the crown, pneumonia, etc., I read about intercostal neurosis
