 [ Symptoms ] i have a hard lump in my left nostril on the wall between nostrils should i be concerned  it is not painful [ Disease ] mmm probably not if this gets bothersome in terms of pain or bleeding or blocking sinus drainage then i would definitely recommend you get it checked out by a physician if it persists for more than a few weeks you may also want to get it checked out it is rare to get cancer in that area though not unheard of but i would consider that a longshot more likely it is a cyst or something similar to a zit as always if you find this lump worrisome make an appointment with your primary healthcare provider and have it looked at take care
