Thank you for that information-I really appreciate your help.
At the moment,it seems that trying LDN is simpler than waiting for any medical help regarding CCSVI......
I'm lucky living in London and being treated at the National Hospital,but I have never been offered anything(because I'm SPMS) apart from a Baclofen pump in June. This has had no effect at all really which is why I have to find any answers before things get too bad.
So-fingers crossed and thanks again
