Here's one that came to mind from last December (Christmas miracle):
My own CCSVI experience has been very positive. I still have MS ups-and-downs but I no longer have the desperate very-ill-feeling fatigue. I also have vision improvements, minimal residual foot drop disappeared for the first time in 5+ years, cogfog improvements, appetite, posture and core strength, and hearing/tinnitus. Numbness in my arm improved but returned but is gone again.
I hope this is helpful to your mom. One thing, the "3 out of 5" was probably referring to 3 out of 5 of the Zamboni criteria, which is a way of measuring the effects of the blockages on the blood flow/hemodynamics. There are three main veins involved in CCSVI: the left jugular, right jugular and the azygous. There are also the iliac and the renal veins that, if blocked, can complicate the azygous drainage. But the "3 out of 5" Zamboni criteria does not tell you how many veins are blocked, only there is some blockage interfering with the blood flow.
