I'm sorry you're in so much pain, I know how much it sucks.
I'm 43 and had a full hysterectomy, and removal of both ovaries, 5 weeks ago.
Before the procedure I was in constant pain and constant pain medication! I felt drained and groggy, suffered from dibillitating migraines and mood swings, all side effects from the meds I was on.
Two specialists advised the hysterectomy as endo was so widespread that it was covering everything and it would have been too difficult and dangerous to try and excise it all.
I too was worried, having read a lot of horror stories about hysterectomies online but once I started talking to people about it, in real life, I found about 8 people I knew, who had also had one done and, to a person, they all said it was the best thing they could have done and it had given them their lives back!
Turns out it was doubly great for me as my stepmom advised me, when I told her I was having the op, that my biological mother had also had one done, as she'd been diagnosed with one of the female cancers, she wasn't sure which one, so there's a good possibility that I dodged a bullet in that regard.
3 1/2 weeks after the op, I was very worried that the pain was back, as bad as before and that I was having crazy hot flushes. Turns out that I'd developed a bladder infection and had a raging fever! I was so worried that the surgery hadn't worked, as I knew there was a chance of this going in.
I'm now on my 2nd lot of antibiotics (first type didn't work) and, now that the post op pain and the bladder infection pain has mostly gone, it feels so much better! The pain is a pretty much gone (I suspect it will be completely gone by the time I finish my antibiotics) and I'm off pretty much all the meds I was on, so no longer feel like a zombie with mood swings 😏
I've still got a way to go, in regards to recovery, and it still feels odd to think that I can't have any more children... not that I probably would have but options and all that, but with the reduced pain and no chances of a lot of the hidden female cancers, I feel I've made the right decision to have the hysterectomy and excision!
Sorry for the long reply, I just thought it best to give you as much information as possible, as I know only too well the worries and thoughts which must be going through your mind right now.
