Wanting advice about possible MS

Hi guys, 27 I dunno if I am in the right place.
Shingles 2019
Flu vaccine 2020 and then after that it started I was diagnosed with labthythinits at the time. My left ear had a build up. Following this
I have had lumber puncture -2020 clear and CT
Recently mri of spine, brain and neck - nothing showing
However, I get balance issues , occasional speech problems, I have been low on B12, I got infections and been taking supplements.
And my left eye is giving me problems I dunno if this is all related or what? I have been to doctor so many times but it’s affecting me so much I was wondering if any one can help? Or any advice appreciated
