I had Vaser lipo and now need a touch up?

I had vaser lipo on my tummy 1 year ago. There was a lump left. I was told to massage and try rio blush (which is so painful). They have finally given me a touch up and removed the lump (above belly button). They did this with no sedation it was not nice. I was traumatised the next day and had visions of this giant wand being waved about in my face and I could feel the burning! Anyway, as it was just a touch up how long do I need to wear garment and how much swelling will there be?
