How frustrating for you. I'm sorry you are experiencing all of this and yet don't have any answers from you physician(s).

First of all, it is not an ignorant question in any way.

I can't reassure you that the spot that was seen is from normal aging. I have never heard of this occurring but I'm a patient not a medical professional. I do know that lesions can happen in other diseases, from viruses, migraines, and head traumas.

You mentioned that you hang out in the MG forum. Did the doctor(s) rule out MG? What types of specialists have you seen?

Sometimes it takes a long time to get a diagnosis of not only MS but other conditions as well. Something isn't quite right and from what you have told us so far, IMO, it doesn't sound "functional."

Hang in there and let us know what happens and how you are doing.
