about 2 months ago noticed swelling on top of and to the left side of nasal septum? the inflammation appears to be in the skin....no nevi, no redness, no discharge, no bleeding on the outside or inside the skin, no unusual sneezing.....its makes my nose look a little crooked. any suspicions on what it could be? I had a 3 month cortisone shot for allergies about 3 weeks ago but I noticed the swelling before the shot.
