What have you tried for the plantar fasciitis? If you're looking at steroid injections, then you've probably tried plenty already, but just in case:
I started getting it at 18 weeks, and the thing that has helped the most is getting arch support in all my shoes/slippers, and wearing these arch support splint thingies around the house. They come with multiple sizes of gel inserts so you can adjust your support level, and it's made a massive difference for me
After trying just about everything posted in here, the thing that finally did the trick for me was some 24/7 arch supports that fasten around your foot like this. Never could get the foot boot to stay on at night. Everyone has different results with different techniques though. Good luck, it sucks.
I use the arch support straps, in my floppy-ass Lollys, linked below.
(Please feel free to order them from NOT Amazon, but here's the Amazon link anyway):

I have extreme overpronating fallen arches. My feet look like fleshy canoes. I wear custom orthotics everywhere. Standing in the shower without them can be excruciating.
Anyway my full sole customs were too tight in the toe area in the Lolly boots and created more pronation, hammer toe effect, and plantar fasciatis.
My half sole ones made the heel to high, soI settled on those straps and goddamn did I level up! I really wasn't living or skating until I could hit edges with a semi-functional feet and ankles compared to the deflated balloon animals I was struggling on before.
I now wear these straps around the house barefoot when I can't be bothered to wear birkinstocks inside.
I've never posted a link before so here's hoping it works out! The arch support is adjustable and the straps are decently comfy.
Bruh...
First, get these and wear them in every shoe: https://www.amazon.com/Arch-Support-Brace-Vive-Compression/dp/B01IBTX95E
Then, wear these while you sleep: https://www.amazon.com/SB-SOX-Compression-Sleeves-Women/dp/B01MFEBO3V
Then, graduate to these insoles when you regularly wake up without your heel killing you: https://www.amazon.com/Superfeet-Mens-Orange-Premium-Insoles/dp/B001FQIMVM
Outside of really niche brands, New Balance seems to have the best shoes for it. This condition suuuuucks. Do what you can to treat it. The arch supports will likely make it at least functional.
