Ray,
I don’t know if you’ve visited the “INF" section of this website about the research/treatment being given at Loma Linda University and Medical Center in Calif. Their claims and testimonials, though limited, make it sound too good to be true. Which we usually need to be careful of. But LL is a highly respected, legitimate medical university and I want to believe that they would not risk that reputation by running a scam. But you never know.

I am hoping to go to Loma Linda for the initial evaluation and treatment using the INF, Intranural Facilitation Therapy. https://lluh.org/services/neuropathic-therapy-center/blog/what-you-need-know-about-intraneural-facilitation-inf

I live about 7 hours away in the Silicon Valley area of Calif. But I starting to have the numbness balance issue on and off, some days pretty bad. I'm having some issues trying to get someone to drive me there since I’m getting leery of my driving abilities, and my circle of friends is now very limited, since about 7 of my close friends have left Calif in the past few years. But that’s another story.

So since you were talking about research, I thought I’d send this to you. Have a great 4th! I enjoy you writings.

Dave
