Hi, could I have seroma? Or something else at 22 days post tummy tuck. Yesterday, I started leaking brown fluid through the lower incision. I then had a blister on my hip with fluid that was starting to seep out. Today, my surgeon has opened my incision at both of my hips, pressed on my tummy and a lot of fluid, was expelled from both hips - this does not appear to be typical aspiration of seroma? Is this a seroma? Would it really be that large to span my whole stomach area? What is the difference between a seroma and lymphocele? I forgot to ask questions!
