Jetsetter, I'm in a similar situation right now.
I lived in the UK from 2002-2005. I gave birth to my first son on the NHS and it was absolutely horrendous. I've been left with permanent damage from the birth and spent a very long time fighting with my hospital over whether or not I deserved the care I knew I needed.
We moved back to the US in 2005, and in the US I've had another child under very bad circumstances. I developed very severe preeclampsia and he was born early.
We were thinking about going back to the UK anyway, but I am now 12 weeks pregnant and will be moving back to England within the next month, as soon as I get my visa done and some goodbyes said. We are moving, in large part, because of the medical system - and I'd have laughed in your face if you told me 5 years ago that I'd be doing this.
I've had a lot of medical care in the last 5 years in the US, and have seen a lot more of the ugly side of things simply because I've needed more care than I ever did before. I've had a few surgeries, my son was a preemie and has also had surgeries, and we've just been very involved in health care lately.
A: It has cost us a bloody fortune. B: I am not convinced I got better care here than I would have in the UK.
The rooms are nicer here. Nice and big and private. The spaces are bigger and brighter. I got a lot more fancy tests done, saw a lot more specialists. And spent a lot more money.
In hindsight, I look at my bad NHS experiences differently now. I know I had very bad luck and just got some real fruit-loop doctors who didn't care about me. (That happens in the US too). But the biggest difference is that I was new to the UK, pregnant for the first time and not very sure of myself, not confident in my ability to navigate the system. I therefore stayed quiet in situations where, had I been in the US, I'd have been ripping someone a new orifice.
I'm a super high-risk pregnancy, and even though I'm still scared of going back simply because of all the bad NHS memories, I'm letting my head win over my heart on this one, and I'm confident I'll get good care. For starters, I'm going to fight for it if I don't get it initially. I'm very well educated on my condition, I'm familiar enough with the UK and the NHS now that I have more confidence in navigating their world, and I'm confident that, even if it takes a while, I'll find myself connected to one of the many, many, MANY doctors out there who really do care, who are lovely, who are smart and good at what they do.
Hope all of that made sense, I know it is quite long and I only intended it to be a sentence or two.
