Thank you @johnbishop! I appreciate you taking the time to respond, and will look at the info links you provide.
Never heard of MRT, but sounds interesting!

In my case, I know that the tumor was crushing the nerves inside the spine canal, but I only became aware of it when I could no longer jump (used to be a competitive volleyball player).
Meanwhile, 3 years went by, with 7 different doctors each giving me a different diagnosis, before they did an MRI and found the tumor. By then, it had caused a lot of damage. I think I've recovered about 80% of my mobility through exercise, but I'm afraid the NP is not going away EVER.

Today, I came across an ad for Nooro Foot Massager, have seen a ton of new gadgets hit the market (never tried any of them), but I figured that some advancements would have been made since my tumor removal.

When googling reviews for the Nooro, this forum popped up, and I decided to investigate. It's interesting to see how many different situations are out there, and the different approaches and methods people try. While we're all in bad situation, it's great to see that I'm not the only one with this condition, so hopefully someone will come up with a cure/solution for it during our lifetime.

Again, I appreciate your help, and will do more reading, especially on what you've kindly provided.
