Legal action against all this medical negligence... How to go about it?

[CofG]

Has anyone ever tried to take legal action against medical negligence??

I was never mentioned the possibility that my ovarian cyst and fibroid might have been endometriosis. Was never diagnosed with it despite my many years of suffering with PMS and heavy bleeding etc. I was totally against surgery to remove ovary and womb and after a year and a half of trying to reverse it with nutrition, it didn't make a difference. Never was I offered progesterone to try and counteract the growths. Never were my hormones tested. Never was I told that if an endo specialist sonographer viewed the MRI, they could diagnose an endometrioma through the MRI. Surgeon said that my cyst could be cancerous (sowing seeds of fear) but said they could not do a biopsy or know until they went in to remove it and send it to the lab. He said they could not see what type of cyst it was from the MRI yet 3 years later when I had another MRI, the endo specialist said that they can see and diagnose an endometrioma from an MRI...

I decided to have the hysterectomy and I developed a pulmonary embolism 6 days after because I wasn't given anticoagulant injections to take home. That mistake has had such profound consequences not to mention having to be on it for life now. I was never offered HRT or even just progesterone even though they discovered the endo during that surgery and they try to scrape what they could. The cyst turned out to be an endometrioma and benign so that was a relief but they could have told me this from the MRI and I would have declined the surgery.

7 months after a new cyst was discovered in the healthy ovary they left behind (surgeon could have removed both ovaries if he had had any slight training on endometriosis as it would have prevented the new cyst at least) They have been keeping an eye on it without hormonal treatment offered still. 3 years later they finally refer me to an endo specialist who is still not offering hormonal treatment and since I don't want surgery, she says to see her again in a year. In the meantime, the endo keeps growing and causing more issues. I feel like I'm losing my mind with cognitive decline, anxiety, panic attacks, palpitations, can't concentrate or learn anything new. I can't remember things or names or faces. I say the wrong words constantly. My speech is getting sloppier and sloppier each day. My hearing issues got worse 6 months after surgery with sudden onset of Meniere's and now I get dizzy and have vertigo often. Endo specialist finally says that cognitive issues can reflect menopause but still she didn't offer HRT. I have had to now chase her to ask for HRT. Every time I went to the GP to tell her that I feel I am losing my mind, she says that I just have too much on my mind, that English is not my first language so that would explain my difficulties expressing myself in English even though I never had this problem before surgery! That they could prescribe an antidepressant etc etc. Why are they not able to connect the dots and possibly think that I might be menopausal?????

Seriously??? Should I be trying to seek legal action against them? Because it is not right that they mess up our lives just because there is a lack of education on basic aspects of women's health... Why has no one ever mentioned HRT??? especially after my surgery??? Now I feel that everything is out of control and so much damage has been caused and so many women out there who are suffering like this and same mistakes are being made... WHAT DOES ANYONE SUGGEST WE DO??????????????
