i am 17 and Since January I've had a stomach flu, strep, a double ear infection, a severe upper respiratory infection, and some other little things(colds ect). Recently, I have noticed little things I dealt with before getting worse; such as being able to catch my breath, shortness of breath to a point I could not breath or talk at all, nausea, tightness in my chest almost like someone is squeezing me, and a few others. when I was born the doctors said I had asthma but I never had any flare ups unless I am really sick but now even simple things I become out of breath. the worst experience I had today which made my coach tell me I am benched until I figure out what is going on, I was going through the color guard routine and where we are. I had to run/sprint/jog/march through this and he made us run a lap around the field because we were not sounding off, not even through 1/4 of the lap I could not breathe at all. I felt as if someone was strangling me and crushing me. I felt very heavy chested, wheezing very hard and loud, could not catch my breath for almost 10-15 minutes. Could this be the asthma worsening or something different or both?
