What is this white bump in my nose?

Ive noticed this white bump in my nostril...I get allergies frequently and my nose can get raw inside from all the itching I do, I just thought I would include this because the pain first started when I had a bad nose itch attack from allergies. I thought the bump was originally a pimple inside my nose and I tried to scrape it off but I just end up hurting myself and months later its still there, its more annoying than anything because it didnt used to be there and now it wont go away..I scrape it and it just scabs up and its just going in circles..I even had my boyfriend try to use tweezers to get it out as strange as that sounds but I'm so annoyed this bump has been there for so long...any ideas what this could be?
