Hi Cliffman,
I am sorry you are going through this experience.
Some important insights have been offered. Both are worth looking into, for sure. Many doctors still do not admit to the potential damage of use of the antibiotics mentioned by mrsD.
I hope you are being followed closely. Is your neurologist aware of the rapid spreading? If not, please let your neurologist know. It's important to get neurology working at finding the cause especially when spreading so quickly.
I know from experience, not all neurology departments act quickly; however, please at least be sure your doctors know what's happening, especially if you are in between appointments.
Keep reaching out about this. It must be very frightening, frustrating and more.
