Hi ! sorry about my English. I had liposuction on abdomen , arms and back one month ago , I am worried because my abdomen is very lumpy , I have read it is normal and it heal with massage and time . I am more worried because I have a thick , long dent underarm , it looks bigger in person actualy . I lost about 10 cms on my abdomen but I dont see any difference on the fat of my arms , they look almost the same , will be this dent permanent?solution? How long can it take to heal?
