can multiple sclerosis occur without auto immune problems?

i was in a car wreck last year dec 7 and a soon aftr it i had problems. alot of them. numbness tingling miagrains ear pain dizziness uncontrolable mucle stiffening hearing loss eye site problem and pain. i black out alot and have"psuedoseizures" and more symptoms just keep coming with out warning and 2 days ago i fainted and hit my head real hard aginst a wall. i odnt know what caused it didnt know it happened. my top right back of my head smashed the windshield after my seatbelt unhooked. so i wasnt ejected. it smashed my neck down and hyperstretched my neck onto my shoulder. every symptom lies with my shoulder and arm. when thos start everyting eles start inmy whole body. recently also my tmj is now unbareable. peeing problems and glass feeling in my fingers which shoots pain down into my palms. anyways theres no auto immune history in my family i know of what gives?
i am seeing a neurologist already. he say sounds like slipped disk or pinnched nerve yes but how can it be soooooo extreme to where i can take care of my child anymore? i constantly sleep and have sleeping difficulties from them. my family hates me and my bfs family too because they see me worthless and whinny to them they dont understand what i feel and i dont eighther at the same time but they think its an excuse because my child is 2 months old. and im lazy. i constantly yell at them caz of it leave me alone and get off my back and then after getting them away my symptoms flop me on the floor paralized or flopping.
but consious durring my "seizures"
