Had Total Hysterectomy. Bleeding From Fibroid. History Of Endometriosis. Ureter Damaged. Have Bloating. Treatment?

Hi, I had total hysterectomy 6 weeks ago due to excessive bleeding from a 500 gram fibroid and a previous history of severe endometriosis. Unfortunately, there were complications during the surgery. My ureter was damaged so therefore one of my kidneys did not work. Five days later they inserted a Stein which stayed in for 5 weeks and was removed 5 days ago. My bloating is incredible and I cannot make my stomach go down. I am an extremely fit person and am struggling with this severe bloating. I look pregnant 24/7. My bowels have nearly gone back to normal, however, I still feel like I am peeing through a needle. How long is this bloating going to last and is there something I can do about it. I am also not a bit eater, especially when I am not in training. I am seeing my gyno this week and hoping to get some answers. Can you help.
