I am a hostel student, I experienced difficult in breathing about 3 weeks ago, it is not wheezing or have weird sound..It just I have to take a deep deep breath by mouth every few normal breath to make the lung feel comfortable; however, the lung sometimes not satisfied even I take a very deep breath in. When I sleep, it is all okay and normal...I do not have dizziness, sweating, fever, chest pain but occasional cough when I exhale in a deep breath..and my nose get blocked quite a long time due to sneezing.. Furthermore, sometimes I have a weird sensation under my left ribcage when I breath in deeply and raise my shoulder..It is like something moving from one place to another place with will return to its original place when I exhale not relax my abdominal muscle... Last, the weirdest things is, all the above symptoms dissappear when I went home last week and come back again when I back to my hostel, can this cause by environment or air quality? Can u please help me by telling what wrongs with me? I am deeply worry, thank you!
