I had unexplained neurological symptoms starting in 1964, that would come and go, but I didn't seek a DX until 1974, my PCP thought MS right away but was DX with Periferal Neuopathy at that time.

The following year Doc sent me to a Neuro for tests. The Neuro put me in the hospital and did many tests. The myliogram/LP came back positive for a demylinating disease and Neuro, putting all the tests together, DXed me with MS, in 1976.
