Hi. On monday night I was trying to go to sleep and I started having trouble breathing. I couldn't get a full breathe in. Or that is what it felt like. Sometimes I can but I always feel like my lungs are tight. It has continued for three days now. I am 18 and have been smoking for a year and a half, though I am trying to quit. I recently got off a steroid for eczema and an antibiotic for staff. Usually I can breathe best in the day, it doesn't even really bother me. In fact even during weight lifting and other activities I feel fine. However around 9 or 10 every night it gets bad and I have difficulty breathing. It is also hard to burp. I am going to go to the doctor on Monday if it doesn't clear up. Does anyone have any idea what this could be? Or how i could fix it?
