Kenalog injections post-rhinoplasty: how long until they work?

I had my rhinoplasty 7 months ago and 4 days ago i had 2 shots of kenalog, one on the left side of my nose and one on the tip to reduce the swelling of a 'polly break' I have a few questions. 1) How good are kenlog steroids at desloving bulky hard scar tissue on the tip 7 months down the line? 2) Its been 4 days, and ive seen no differance, is this normal? How long till they take effect? 3) If i keep touching my nose, will this move the fluid into a differant place and not be effective?
