Hello. I am thirteen years old and I have noticed since this morning that I feel like there is a lump in the right side of my throat so I am compelled to swallow often, even though it won't dislodge. I believe I may have felt this lump before but it went away soon after. I feel some discomfort in what I believe is the bronchial tube leading to my right lung. I had a cold about four weeks ago and I noticed that even now, I sometimes bring up green mucus even though I am no longer sick. I am also feeling slight discomfort in my right lung and for quite a few months or so, I have been sensitive to strong perfumes, smoke, etc. When I inhale them, I feel like I can't breathe at all. Also, whenever I poke between my ribs where my right lung is, it feels funny. Nobody around me smokes, my mother has sinus problems and my baby sister was recently diagnosed with asthma. Can you help me with this problem please?
