Im new Palm Bay FL

I just have a question for those of you that have had the surgery. Did the extra skin you had when you lost the weight go away or did it have to be removed? I lost 100+ pounds not once not twice but THREE times. Now I am kinda thin on top but has flabby arms and really big flabby legs. When I sit down my fat kinda flattens out and my one leg is wider than my waist. I am down to 175 now and feel like I will never get my legs back to normal. If anyone knows of a way to get rid of the extra skin please let me know. Just for the record the reason I am here is because I have been obese most of my life. I was 285 pound in jr high. This is the smallest I have been since Elemetary School.
