I had chin lipo about two months ago and still have a bump under my chin. Doctor assured me it's just swelling and should go down. However I've had swelling from lipo before and this is very different. When I press against it, it seems like fluid is being shifted inside the area. I'm concerned this is a seroma and brought it up to my provider and he dismissed the idea. I emailed them again stating that I thought it was a seroma and should be drained. I'm waiting to hear back. Any thoughts?
