In my experience, most doctors will refuse if you are in child-bearing age range, regardless of what you want, even if you are adamant you've never and won't want kids. The fact is, they just tell you to deal with it...tho once you're older they will be more likely. I don't know if being in your 40s will help you on this, maybe.
I do know when I was in my early to mid 30s, with similar issues though some not as severe, I was flat-out told by drs they would, and any dr, would refuse to give me a hysterectomy cuz of my age, unless it was a life/death illness type of emergency surgery...cuz "I might want kids." When I said, I am an adult and know that afterwards, even IF I changed my mind, wouldn't be able to have kids, they refused. I said but it's my body and healthcare!! They don't care. I said I will never have kids, never wanted them, would never be with anyone that would want them, that my periods were affecting me greatly. But nope...must have intact lady parts cuz you are a girl and that's your only value and omg, gasp, what if a MAN (husband, bf, partner) wanted kids, how selfish.
However, I had a snide dr said they could possibly get me approved for one if they spun it as I was having severe mental health disability issues. So great, put up with it, or further be labeled crazy, shrugged off etc. no win either way. I suppose however if you have a lot of money to pay on your own, they'd take your money and do it.
Also, this wasn't happening then, but ffs, if I would've been trans, I could've had the damn internal lady parts cut off in a jiffy! But if you are girl, nope, you MUST keep them til you're too old for a baby cuz that's what SOCIETY wants and feels better from. Further proof your body is not really yours and further proof I think humans are the devil, abusive, controlling jerks. Sorry.
I say it'll be easier the older you get, maybe. But they are gonna fight it if they think you are still capable of having a baby and/or sex, even if you say otherwise and regardless of it being your body.
I'm sure there are some good drs out there, just keep looking. I gave up cuz I would rather die in pain than ever go to a dr except for some things. Never listened to anyway so feels a lost cause and let God heal me (and me doing things) or I just suffer, mostly silently, as society does not like you to talk about pain physical or mental, or if you do it's go take 20pills and shut up anyway. Modern medicine is barbaric and antithesis to health (power and money and torture imo); obviously not all.
I say, keep speaking up. I didn't; gave up cuz of hundreds of poor experiences. I hope your pain and misery eases somehow! It sucks to live in a biological body; maybe we won't have to one day, omg it'd be awesome you wouldn't be programmed to feel pain (physically, at least)! In a few generations that might be an option so at least maybe future generations won't have to deal with it.
