I know of tons of people who got pelvic floor issues after covid
this is like my fourth or fifth time on this forum saying something is caused by covid and I think people might think im obsessed but im really not. but it's noteworthy to see all these similar issues start for many people around the same time.
anyways.
I would recommend figuring out if you can safely take methylene blue in decent doses. you say you get a UTI every year, MB is good for that and maybe will help
you probably can do exercises too for your pelvic floor issues
