I’m upset to report that my polish friends mum who had balloon angioplasty for the 2nd time nearly a month ago has had some very bad worsening symptoms

From what I understand she now has extreme stiffness and weakness which is making walking impossible before she could walk with support (I’d say she had EDSS 0f 5.5-6.0)
Last operation she had just a balloon which caused the vein to widen to much to insert a stent,
I am very worried about what sadly happened to rici might of happened to her and could happen to someone else,
As I understand she is to scared to go back for more treatment now
Has anyone had a similar problem apart from rici where the vein has become to wide to place a stent ?
Any thoughts on this ?
