I'm a bit confused about my recent test results and could use some advice. My spirometry report came back normal, but my FeNO level is around 35. I'm not sure what this could mean. Could it be a sign of asthma or allergies, or maybe something else? Also, my SPO2 level is consistently at 98. Would love to get a better understanding of all this.

this test indicates the amount of nitric oxide exhaled, which is used to diagnose asthma. since your feno value is increased it might be asthma, but not a confirmatory test

I'm a 20-year-old student and I've been dealing with bronchitis for the past 10 years. Every April, I struggle with breathlessness and a lot of mucus in my chest, it gets pretty congested. I don't eat anything that would increase mucus, just stick to simple homemade foods, but it keeps happening. I use a nebulizer to help out, but I'm worried if this is something I'm going to have to deal with for life. Do you know if there's any way to cure this or make it better?

yes it is for years till the symptoms cure
