All at your own risk and talk it through with your doc:
Bruising can be reduced (many believe) with Bromelain 500 mg twice a day, Arnica montana (Boiron brand) dose 30C (take 4 small tablets sublingually, 4 times a day), vitamin C 500 mg (3 times a day)... some start 1 week before surgery...
bromelain may reduce swelling, bruising, healing time, and pain following physical injuries and surgery.
Bromelain is also part of fresh pineapple.
Its now commonly recommended by quite a few surgeons in plastic surgery, and srs.
People in sports use it, too, to deal with swelling.
You might think about external application of plants, some draw out liquid...
you might read up which ones, possibly onions for example.
Keep them away from wounds...
