Hello, I Am A 16-year Old Female Who Has Been

Hello, I am a 16-year old female who has been dealing with allergies for a couple years now. Recently (About 6 months) when breathing I've noticed almost a shaking feelings when I exhale, in my throat. It almost feels like I have constant mucus, that I can't clear out. I've noticed I tend to clear my throat a lot in the mornings and at night, and sometimes I also get this feeling in my lungs. I am NOT coughing, I don't feel the need to cough or anything, which is the confusing part. If I could get an answer, that would be great!
