Ear-Nose-Throat Problems

Hi, I went to a high altitude trek of 15000 feet in a snowy region 4 months back.. but after that, I feel a slight discomfort in breathing, sort of nasal congestion but without cold nor running nose.  Like one side is completely blocked and sometimes the other side.. It's doesn't feel like a serious problem, I feel normal.. but there's a slight discomfort at times... What could it be? Please help...
