I was told i have a ‘High Probability’ of having Multiple Sclerosis?

Im so confused what does this even mean?

Background Info:
1.5 years ago started developing symptoms of dizziness, extreme fatigue, pins and needles, numbness (especially in my feet, my left foot is still completely numb) memory and speech difficulties. I got referred to a neurologist who did a MRI it shows many lesions (T2 hyper-intensities) bilaterally. So he did a full spinal MRI no lesions in my spine and i don’t have optic neuritis.
I had a follow up appointment 2 days ago and he said my spinal MRI was clear so i asked does it rule out MS? he said "no there is a high probability you have MS" So now im being sent to have nerve conduction tests and a follow up MRI in 3 months time.

I feel very frustrated, I know he is trying to help but he has not helped my symptoms at all. The fatigue is ruining my life i spend more time in bed then what i do out of bed, I have had to cut down shift at work. I guess i would feel better if he was doing something for my symptoms as well as trying to diagnose me.

So how should i take this information? Does he really think I have MS? Sorry this is so long im just really confused at the moment.
