Hi boots,
I just wanted to Welcome you to the forum. NT is a great place. Just give us time to get to know you. We love new people.
So sorry to hear about your Mom's passing. I see you posted on the Parkinson's forum. I hope you find the answers to your questions. If a doctor ignores you then change doctors. We all need to know what is wrong with us when we have symptoms and we don't know the cause.
Good luck to you and nice to meet you.
