That's a tough choice Neil. Fingolomid as I understand it is the oral version of the MS drug that is currently in clinical trials?
You know your body better than anyone else, and making a drug decision is definitely a highly personalized one.
For example, if I had the chance to try Fingolomid, even if it's a 2 in 3 chance, you have your neuro asking you more than 1 time if you're interested in trying this, I'd personally jump on the opportunity. I'm also in a very much different situation than you, as far as my age and the disease, since it's so individualized.
Glad to hear that you do have the insurance now to go with a DMD however. If you choose to go that route, I don't think it's a bad decision at all. You'll know in your heart what is the right decision for you.
