Thinking I have MS

I am 26 years old and have been to the hospital 17 times in 2 years because of my left side of my chest always hurts and my left arm always hurts and feels numb to my fingers , having numbness in my forehead everyday , memory problems and recently my left eye started to feel like it's twitching and won't go away and now my left leg feels numb and tingling all the time and bad stomach pains. Just wish I could find answers. Went to hospital a week ago and they said my reflexes are abnormal and he checked me for a brain tumor with a CT scan that's it and told me no tumor but thinks I have MS and just want someone's thought on my case cause I'm honestly going crazy cause I may look alright on the outside but my insides feel like I'm dying. Please someone help with information ...
