Swollen inner nostril??

Hi ladies,

One of my nasal passages (the right one) has been bothering me for the past few days by being seemingly congested and when I was wiping it with a tissue traces of blood would come with regular mucous (I don’t have a cold, just like normal mucous). So then I did some inspecting in the mirror with a flashlight and found that nostril is super swollen and red inside and is almost completely blocked by the swelling. It bleeds a little from certain spots when I try to gently clean out the inside with a tissue. I don’t have allergies...any idea what this could be? I’m 17 btw.

I couldn’t really get a good picture but that’s a blurry image of the inside of my nostril. The dark line is where the two sides of my nostril are meeting.
