Will carboxy theraphy work for hard lump left near belly button after liposuction? (photos)

i had liposuction on my lower back and small area around belly button, now i have a hard lump on my belly and uneven back i had lymphatic massages done with not much improvement, the lady that did my massages also does the carboxy theraphy and told me that that will help a lot with dissolving the lump and unevenness.
