The insid of my nostrils will swell up. Should I go back to my doctors

First it was my right nostril now its my left my nose feels clogged from the left side now, should I see my doctor. Ive been sneezing a lot but I dont even have a cold or even have got one this year... my throat felt scratchy like 2 weeks ago still no cold so I searched up seasonal allergies symptoms and I feel like ive got that but From what I kno ive never had allergies ugh I was just at my doctor a week ago  and she said there is no problem in my results  she sees this more as a mental health issue, I dont understand im afraid its a serious infection or cancer Ive got Benadryl but im afraid to take it 

Hi Stacey could it be hay fever 🤒 

Thats what I was thinking! One side of my nose will unclogg then the other side gets clogged 🤦🏾‍♂️
