Pelvic pain

I’m at a loss and need help. Bit of background is protectomy jan 2017 surgery went well was looking forward to feeling well. However I started get pelvic pain nothing major but had a scan it showed a 12cm cyst on ovary. So they drained it... it then re filled and burst since then I have had major pelvic and back pain is one free fluid was found in pelvis it was drained long story short fluid keeps being drained then returning!! I am in severe pain and we don’t know why I am currently in bed on morphine. I can’t keep being like this I have two children and a job!
Could it be dropped organs after the rectal removal?
Could it be I was caught in surgery and have an ongoing leak? I get tummy swelling worse after eating.

Help

I am back under him recently after a year of being with gynaecologists they handed me back. I’m seeing my him tomorrow as an emergency just was hoping to go with some ideas of what it maybe could be. Thanks for your reply glad your well a few years on. I’m going to cry if they say it adhesions because it’s affected my life so much.
