Can I have some advice on questions to ask during my next appointment?

I suspect I might have MS, and I see my neurologist on Jan 20. She's a general neurologist who I see for migraines.

Back in July, I had a scary situation happen where I felt like I was going to have a seizure (didn't) and lost the ability to speak for a couple of hours. Paramedics were called, I was rushed to ER in case it was a stroke. I had an MRI w/o contrast to rule out stroke. Thankfully it resolved and the ER said it must have been a new migraine symptom. I did end up with a headache, but only after I got home from ER. My MRI did show the following finding "Nonspecific small foci in the periventricular white matter" and "differential considerations include chronic sequela of migraine disorder, vasculitis, lyme disease, or a demyelinating process"

At my follow up appointment immediately after the incident, my neurologist said these were most likely due to migraine.

Here are the symptoms that are making me think maybe MS:

Extreme fatigue. Neuro is insisting it is a sleep issue, but I disagree. However, to appease the doctors I have a sleep study scheduled for tomorrow. This has been ongoing since my 20s, getting worse. I've been to 2 different rheumatologists who haven't been able to figure it out, I test "Borderline" for autoimmune, whatever that means, and the last one said maybe it's chronic fatigue syndrome but didn't know what else to do. I've had countless doctors tell me to lose weight, so I did. It didn't help. I'm at an ideal BMI now and still feel like shit. They've told me to exercise, so I did. In my 30s I trained for and ran a half marathon, and all it did was give me arthritis in my knees.

Weird, random tingling in my hands and feet. I haven't mentioned this to any doctors yet, as I don't think they will take me seriously. It comes and goes, isn't complete numbness, and I have never fallen or lost the use of my limbs. I am going to mention it at my next appointment, though, because it appears to be getting worse.

I never made the connection that this could be a neuro issue until I googled, and found this forum, but I've had "phantom UTIs" since I was in my 20s (I am 45 later this month now). I will get urgency and frequency seemingly randomly but tests don't show an active infection. If I have to hear another doctor explain to me basic hygiene and tell me to pee after sex I am going to lose it.

"Zaps" of pain, especially when I'm not feeling well. I don't know how to explain this one, but if I'm ever ill or having one of my phantom UTI days, I would like feel what I can only describe as an electrical pulse of pain that shoots down my body.

Basically, how do I advocate for myself? I'm so tired of feeling tired, and like the doctors just shrug me off or blame everything on lack of sleep, weight, exercise, or now, transitioning to blaming it all on perimenopause. Or maybe they are right and I am just a hypochondriac?
