(((hugs))) I don't know how your speech is at this point, but a speech program helps me immensely on those days and weeks when my hands refuse to cooperate.
Asking why, while allowed, never seems to get me very far in my thinking. It is what it is. Maybe there was a different trial before this one. Would you exchange this trial for another trial instead? Not that we get that choice.
Support groups are important for MS, imo. Others who have been at the point you are, others who aren't as learned as you, yet.
Warm water helps with hands. Limit your stress as much as you can ... I hope you have ppl who help and support you IRL. Thanks for giving us an update, you will feel better and be able to share more with us in the future.
