Can weight be placed on abdominal seroma?

i am 6 weeks post circumferential body lift. I developed a large seroma in my lower ab/pubic are , PS was able to drain out 500 ml and placed a new JP drain. It has been one week and my fluid out put is 75 ml in 24 hour period. I have compression garment on but feel swollen in lower ab/pubic area. I had someone suggest to me to lay flat in bed and place a flat 5 pound weight on the lower ab and see if it helps. Is this safe/effective?
