Look into the company Emcell at emcell.com. They're in Ukraine. Controversial, however they claim that fetal stem cell treatments (used from donated tissue, if that makes a difference to you) - if degeneration of healing systems of the body from MS aren't too far along - will stop MS and regress it, reverse damage/heal/cure it.

Here's their specific page on MS: https://www.emcell.com/treatments/multiple-skleroze/

There are free documentary video(s): https://stemcellsmovie.com/ or https://www.emcellexperience.com/emcell-videos/ - the 2nd video from the top.

Emcell explains that the stem cells they use, from 7-12 weeks, are safe to inject in everyone, as the cells haven't started to differentiate yet into the unique individual - mainly the immune system hasn't started to develop, and that they are the base 1000+ stem cell types that we all start with.

I'll email you too in case you miss this.

Edit to add: They also have a bunch of testimonial videos, including of doctors of patients they had and couldn't help: https://www.youtube.com/channel/UC7FLNCZlZ7ofwOPeclBr-xA - if that helps build your trust towards what they offer, if they seem genuine or not; it's hard to know with new technologies that aren't mainstream, skepticism is healthy - especially when desperate people can be an easy target to try to extract money from - but then if it is indeed safe as they claim (they've supposedly started doing research on fetal stem cells 35-40 years ago, and have been offering them clinically for 30-35 years now) - then it's a decision that probably lands on the question of risk-benefit analysis, ultimately, what do you have to lose?
