I also suffer from neurological health issues (damage from lyme) which is the reason I'm here.
If I understood it correct you haven't got any diagnosis for multiple sclerosis yet? (No MRI and/or Spinal tap taken?)
Please don't make any rushed decisions, if you have ms medication can help you physically, and it can take many years before it gets worse, and during those years it's not unlikely that there will be cures for this illness, I feel quite certain a lot of things will happen in the coming decade. When it comes to understanding about illness and to solve health issues we have been in a linear progress for many years, but I would almost for certain say that this will be more exponential over the coming years.
I'm not trying to dismiss your suffering, believe me I know how it feels to be scared of the future because of health issues.
Ps. I saw you are looking for people to discuss with, I wish I had the energy to get in touch and discuss, but unfortunately my health is to bad. But I still want to share some thoughts.
