For more than a month I sneeze quite a few times right after waking up every morning, some days the sneezing continues for the whole day. I also feel light wheezing in my chest sometimes, in order to clear the wheezing I intentionally cough and when I cough, sometimes light yellowish phlegm chunks come out. I also feel the urge to clear my throat all the time. I also breathe a little heavy after climbing stairs or after doing something that takes a little effort.
