There is a hard lump directly below my incision after a corset lipoplasty and neck liposuction post op. Did my procedure work?

I'm a 40 year old man that had a corset lipoplasty procedure 7 days ago. I am wearing the compression garmet as long as I can. However, at night I remove it unknowingly. The skin incision under my chin has not closed but I believe the underlying skin has. There is a hard very mildly painful lump just under the incision site. I am concerned that I did not get a result from the procedure. It's difficult to tell because I can not (and assuming should not) shave until the incision fully heals.
