Weird neurological symptoms

It all started feb-march of 2024 I started getting twitching all over then one day I woke up and started noticing a clicking in my throat and very mild swallowing issues then I would feel these what felt like adrenaline rush in my forearms but now I realized they were actually tremors and I also started noticing my muscles getting thinner then tremors spread to my legs i would notice them more going down stairs so i scheduled appt with neurologist she said she would send me for mri (normal) and emg i waited to do that to see if symptoms progressed every think stayed the same till about April 2025 so I went back to neurologist she said it was in my head and and referred me to a physiatrist so I scheduled the emg in march came back clean then after that my symptoms started to progress rapidly I noticed the internal tremors got a little worse but then stoped and I only noticed them when I pick up heavy stuff but then I would have dizziness almost every day my memory seems to be getting worse lost some hearing in right side and the weakness in arm and leg seems to be more on the right I also have stiffness on that side including fingers comes and goes but constantly in thumb still functioning neck stiffness I do sigh alot am also a smoker i have vision issues fatigue feels like weakness in legs and arm are getting worse by the day I also have stiffness in my jaw and it tires easily when I chew dry mouth dry eyes bp is low laying down andbthen higher standing I do have low oxygen when sleeping but on bipap for osa oxygen levels seem to be improving little by little I have seen endocrinologist rheumatologist gi all labs normal I did order some labs my self all normal I did order one called vgcc n-type it was normal but close to high just wondering if any has had symptoms like this and any input would be greatly appreciated doctors keep pushing me off it's so frustrating every day I'm miserable because I feel like crap
