Im a 28 year old male and i had lipo done on my stomach about a year ago and i have a lot of scar tissue over my abdomen. So i got a kenalog shot(not too much) mixed with lidocaine injected at an angle(just under my skin) to eat away the scar tissue. i did it march 1 2009 and its now middle of April and i see no change in the shrinkage of scar tissue(which is pretty prevalant) however i don't want to do it again to early then have a dent in my stomach. does anyone know how long it may take to see the atrophy of scar tissue is it too soon? hope someone can help :) thanks!
