Suggest Home Remedy For Swelling Of Abdomen

I am writing on behalf of my husband. He was recently diagnosed with cirrhosis of the liver by his family Dr. He was referred to a gastroenterologist for a paracentesis, which was done this past Friday. We removed the bandage from his abdomen approximately 27 hours later (on Saturday afternoon), and the site began draining, uncontrollably. We went to an emergency room where the attending Dr. put dermabond on the wound. The draining stopped, but my husband s abdomen began swelling on Sunday and into Monday. I called the Dr. who performed the paracentesis and was able to get an appointment for my husband with this Dr. yesterday, Tuesday. The Dr. had an ultrasound and CT scan done yesterday and found no reason for the swelling and prescribed Ciprofloxacin to treat the swelling as an infection, possibly from the dermabond. Late yesterday evening and throughout today, my husband s penis and testicles have become so swollen and sore that he can barely move. My husband is also on a high blood pressure medicine and three (3) different water pills. Is there something that we can do at home to reduce the swelling in his abdomen and genital area? Thank you,
