I have to agree with @ohbygolly. As this is a private hospital and not the NHS, you are now dealing with a scenario that is exactly the same as if a mistake was made in a country where medicine is run for-profit. Instead of having things like PALS and debriefings and investigations into an NHS trust, golly is right that you’ll probably have to sue for answers (and unfortunately that’s happened occasionally even with the NHS), which is what so many people don’t seem to understand.
My heart was breaking when you wrote that you were trying to see your consultant and having a “tough time” with it. I’m sure that’s not an accident on his or her part. They are probably avoiding seeing you, just like they will avoid verbally taking any responsibility for their wrongdoing. I know people who have sued in a situation much like yours (unnecessary surgery with life-long complications) because, in their words, “I just wanted them to admit they were wrong, and they wouldn’t.” And she couldn’t say that sentence without crying.
You have lost your breast. You have lost lymph nodes. You may have some movement difficulty with the arm on that side forever. And it was all unnecessary. You have the right to feel ANYTHING you feel - sad, angry, confused, upset, grief-stricken.
So yes, I would sue. Anyone who gives you some trite shite about how you should just be happy it isn’t cancer and ignore all the rest is being damn insensitive. You have to deal with this every time you take off your shirt for the rest of your life. AND you should definitely have the money to fund the future surgeries you’ll need (replacing the implant in X years, possible scar tissue removal, physio for your arm or possible future lymphedema).
I’m absolutely shocked at how many people voted YABU. I don’t believe people should sue at the drop of a hat, and I even had a mistake during surgery that affected me for years and I didn’t sue (it was an unfortunate mistake, but not really negligence), but this is a completely different level.
