I have a red bump in my nostril i've been stressing over it for a week now it's not a pimple it doesn't hurt and its kind of at the bridge of my nose.

See ENT: If this does not resolve with warm compresses in 2-3 weeks, you may want to see an ent.

Folliculitis: This may be an infected hair follicle, or even a staph infection. Go see an ENT or dermatologist for a thorough evaluation and to get the proper treatment. In the meantime try an over the counter Hydrocortisone and polysporin (bacitracin and polymyxin).
