I want to say hello and welcome you to Neuro Talk. You can talk here, and people will try to help. You have every right to be afraid. Being young makes any neurological problems scarry, as you think it may last. These conditions have help. It is really important to find a doctor able to make a DX. Your doctor was wrong not to do the biopsy. It seems like you believe that physician has put you into a dead end. don't give up. Try to go to a teaching hospital in your area. I hope that folks will respond and give you some names. I do wish you all the best. There is help, but sometimes it takes some real effort to find the right kind of physician. ginnie
