My first MS symptoms happened over 25 years ago. It was a week of slurred speech, fatigue, brain fog and a sort of bit foggy vision at times.
Throughout the years I had fatigue, bits of slurred speech, forgetting words, vertigo, back pain, sciatica and countless other symptoms that I mentioned to my GP and then eventually ignored when nothing much was done about them.
Ten years ago I was in a car accident that seemed to really start symptoms going, then hurt my back to the point that my pain couldn't be ignored.
When I asked my GP over 3 years ago if I had MS, she said no. Eventually she sent me to a neurologist because she just couldn't ignore things any longer. That was 2 1/2 years ago. Since then I've had 3 MRI's and the one that got the diagnosis was the brain scan. I've not had any other other diagnostic procedures as the brain MRI seemed to tell them all they needed. Did go to see a neuro at the local MS clinis who after examining me & an interview confirmed that what I had was SPMS. So no lumbar puncture, no evoked potentials, just a lot of MRI's. In fact, if he had suggested a lumbar puncture I was ready to decline it as totally unnecessary.
