I am vipul and my age is 21, For about 1 weeks now I have been experiencing difficulty sufficiently breathing, especially at night. It's a sensation that I can only describe as a feeling of not being able to get enough air in my lungs or 'a tightness in my chest/airways. It's still apparent during the day but worsens by night. I also have a dry cough accompanied by wheeziness when I inhale and I feel like I might need to phlegm but it hardly ever comes out. On the rare occasions that I do actually phlegm; it's mostly clear and rather sticky.
